made Ireland completely subject to growing British colonial powers in the early 1600s. Forced settlement of newly conquered land and inequitable laws defined life for the Irish under British rule. England had previously conquered Scotland and Wales, leaving many people from western Scotland to seek opportunity in settling about 500,000 acres of newly seized land in Ireland. Some Irish people were displaced to an attempted "reservation". This resulted in Gaelic ties between Scotland and Ireland withering dramatically over the course of the 17th century, including a divergence in the Gaelic language into two distinct languages. In 1641, the Irish were finally able to drive out the English for a short time through a successful rebellion and proclaim the Irish Catholic Confederation, which was allied with the Royalists in the

Ireland thus became an integral part of the United Kingdom, sending around 100 MPs to the House of Commons at Westminster and 28 Irish representative peers to the House of Lords, elected from among their number by the Irish peers themselves, except that Roman Catholic peers were not permitted to take their seats in the Lords.

, who argued that emancipating the Roman Catholics would breach his Coronation Oath. The Roman Catholic hierarchy had endorsed the Union. However the decision to block Catholic Emancipation fatally undermined the appeal of the Union. The slow emancipation of Catholics in Ireland began later the early 1800s. British oppression led to increasing impoverishment and depopulation of Ireland (the island had still not returned to its 1800 population by the early 21st century). Between 1845 and 1849, Ireland experienced a great famine caused by potato blight. However, the British government, in keeping with its laissez-faire ideology, refused to intervene and help the Irish. Also, grain from Ireland continued to be exported abroad, exacerbating the famine. One million Irish died and many emigrated. Ireland's demographics never recovered from this, as large numbers of Irish continued to move away (mainly to the US). The famine and its aftermath led to lasting bitterness in Ireland and increased the desire for

compounded the difficulties. The government urged people to support the confrontation with the UK as a national hardship to be shared by every citizen. Pressures, especially from agricultural producers in Ireland and exporters in the UK, led to an agreement between the two governments in 1938 resolving the dispute. Many infant industries were established during this "economic war". Almost complete import substitution was achieved in many sectors behind a protective tariff barrier. These industries proved valuable during the war years as they reduced the need for imports. Under the terms of resulting Anglo-Irish Trade Agreement, all duties imposed during the previous five years were lifted but Ireland was still entitled to impose tariffs on British imports to protect new Irish "infant" industries. Ireland was to pay a one-off £10 million sum to the United Kingdom (as opposed to annual repayments of £250,000 over 47 more years). Arguably the most significant outcome, however, was the return of so-called "

Articles 2 and 3 and the name ''Ireland''

Ireland adopted a new constitution in 1937. This declared Ireland to be a sovereign, independent state, but did not explicitly declare Ireland to be a republic. However, it did change the name of the state from ''Irish Free State'' to ''Ireland'' (or in the Irish language). It also contained

Increasingly positive relations between the two states required the two states to explore imaginative work-arounds to the disagreement. For example, while the United Kingdom would not agree to refer to Mary Robinson as ''President of Ireland'' on an official visit to Queen Elizabeth II (the first such visit in the two states' history), they agreed to refer to her instead as "President Robinson of Ireland". As a consequence of the Northern Ireland peace process, Articles 2 and 3 were changed in 1999 formalising shared Irish and British citizenship in Northern Ireland, removing the irredentist claim and making provisions for common "[institutions] with executive powers and functions ... in respect of all or any part of the island."


Abdication crisis and the Republic of Ireland Act

The Irish Free State had been governed, at least until 1936, under a form of constitutional monarchy linked to the United Kingdom. The King had a number of symbolically important duties, including exercising the executive (government), executive authority of the state, appointing the cabinet and promulgating the law. However, when Edward VIII proposed to marry Wallis Simpson, an American socialite and divorcée, in 1936, it caused a constitutional crisis across the
British Empire The British Empire comprised the dominions, Crown colony, colonies, protectorates, League of Nations mandate, mandates, and other Dependent territory, territories ruled or administered by the United Kingdom and its predecessor states. It bega ...
. In the chaos that ensued his abdication, the Irish Free State took the opportunity to amend its constitution and remove all of the functions of the King except one: that of representing the state abroad. In 1937, Constitution of Ireland, a new constitution was adopted which entrenched the monarch's diminished role by transferring many of the functions performed by the King until 1936 to a new office of the President of Ireland, who was declared to "take precedence over all other persons in the State". However, the 1937 constitution did not explicitly declare that the state was a republic, nor that the President was head of state. Without explicit mention, the King continued to retain his role in external relations and the Irish Free State continued to be regarded as a member of the British Commonwealth and to be associated with the United Kingdom. During the period from December 1936 to April 1949, it was unclear whether or not the Irish state was a republic or a form of constitutional monarchy and (from 1937) whether its head of state was the President of Ireland (Douglas Hyde until 1945, and Seán T. O'Kelly afterwards) or the

(George VI of the United Kingdom, George VI). The exact constitutional status of the state during this period has been a matter of scholarly and political dispute. The state's ambiguous status ended in 1949, when the Republic of Ireland Act 1948, Republic of Ireland Act stripped the King of his role in external relations and declared that the state may be described as the ''Republic of Ireland''. The decision to do so was sudden and unilateral. However, it did not result in greatly strained relations between Ireland and the United Kingdom. The question of the head of the Irish state from 1936 to 1949 was largely a matter of symbolism and had little practical significance. The UK response was to legislate that it would not grant Northern Ireland to the Irish state without the consent of the
Parliament of Northern Ireland The Parliament of Northern Ireland was the home rule legislature of Northern Ireland, created under the Government of Ireland Act 1920, which sat from 7 June 1921 to 30 March 1972, when it was suspended because of its inability to restore ord ...
(which was unlikely to happen in Unionism in Ireland, unionist-majority Northern Ireland). One practical implication of explicitly declaring the state to be a republic in 1949 was that it automatically terminated the state's membership of the British Commonwealth, in accordance with the rules in operation at the time. However, despite this, the United Kingdom legislated that Irish citizens would retain similar rights to Commonwealth subjects and were not to be regarded as foreigners. The Republic of Ireland Act came into force on 18 April 1949. Ten days later, 28 April 1949, the rules of the Commonwealth of Nations were changed through the London Declaration so that, when India declared itself a republic, it would not have to leave. The prospect of Ireland rejoining the Commonwealth, even today, is still occasionally raised but has never been formally considered by the Irish government.


Toponyms

A minor, though recurring, source of antagonism between Britain and Ireland is the name of the archipelago in which they both are located. Known as the ''British Isles'' in Britain, this name is opposed by most in Ireland and its use is objected to by the Irish Government. A spokesman for the Irish Embassy in London recently said, "The British Isles has a dated ring to it, as if we are still part of the Empire. We are independent, we are not part of Britain, not even in geographical terms. We would discourage its usage .". No consensus on another name for the islands exists. In practice, the two Governments and the shared institutions of the archipelago avoid use of the term, frequently using the more appropriate term ''these islands'' in place of any term.


The Troubles

Political violence broke out in Northern Ireland in 1968 following clashes over a civil rights campaign. The civil rights campaign demanding an end to institutionalised discrimination against Irish nationalism, nationalists by the Unionism in Ireland, unionist Government of Northern Ireland. As the violence escalated, 1969 Northern Ireland riots, rioting and attacks by nationalist and unionist groups began to de-stabilise the province and required the presence of Operation Banner, British troops on the ground. In the wake of the riots, the

expressed its concern about the situation. In a televised broadcast, Taoiseach Jack Lynch stated that the Irish Government could "no longer stand by" while hundreds of people were being injured. This was interpreted as a threat of military intervention. While Exercise Armageddon, a plan for an Irish invasion of Northern Ireland was rejected by the Government of Ireland, a secret Irish government fund of £100,000 was dedicated to helping refugees from the violence. Some more actively nationalist Irish Ministers were tried in 1970 when it emerged that most of the fund had been Arms Crisis, spent covertly on buying arms for nationalists. Angry crowds burned down the Embassy of the United Kingdom, Dublin, British Embassy in Dublin in protest at the shooting by British troops of 13 civilians in Derry, Northern Ireland on Bloody Sunday (1972) and in 1981 protesters tried to storm the British Embassy in response to the IRA hunger strikes of that year. In 1978, the European Court of Human Rights (ECHR) trial ''Ireland v. the United Kingdom'' ruled that the techniques used in interrogating prisoners in Northern Ireland "amounted to a practice of inhuman or degrading treatment, inhuman and degrading treatment", in breach of the European Convention on Human Rights. Throughout the conflict, the Republic of Ireland was primarily crucial for the Provisional Irish Republican Army campaign, IRA campaign against British troops and Ulster_loyalism#Paramilitary_and_vigilante_groups, loyalist paramilitaries. Irish historian Gearóid Ó Faoleán wrote for ''The Irish Times'' that "[t]hroughout the country, Irish republicanism, republicans were as much a part of their communities as any others. Many were involved in the Gaelic Athletic Association, GAA or other local organisations and their neighbours could, to paraphrase [Irish writer Tim Pat Coogan, Tim Pat] Coogan, quietly and approvingly mutter about the 'boys' – and then go off without a qualm the next day to vote for a political party aggressively opposed to the IRA." Shannon Airport and Cork Harbour, Cork and Cobh harbours were used extensively by the Provisional Irish Republican Army arms importation, IRA for arms importation overseas during the early 1970s aided by sympathetic workers on-site. Most IRA training camps were located in the republic, as did safe houses and arms factories. The vast majority of the finances used in the IRA campaign came from criminal and legitimate activities in the Republic of Ireland rather than overseas sources. Large numbers of improvised explosive devices and firearms were manufactured by IRA members and supporters in Southern Ireland and then transported into Northern Ireland and England for use against targets in these regions. For example, one IRA arms factory near Stannaway Road, Dublin, was producing six firearms a day in 1973. An arms factory in the County Dublin village of Donabate in 1975 was described as "a centre for the manufacture of grenades, rockets and mortars." Gelignite stolen from quarries, farms and construction sites in the Republic was behind the 48,000lbs of explosives detonated in Northern Ireland in the first six months of 1973 alone. IRA training ranged from basic small arms and explosives manufacturing to heavy machine guns, overseen by Southern Irish citizens, including a former member of the Defence Forces (Ireland), Irish Defence Forces. Thousands of Irish citizens in the Republic joined the IRA throughout the conflict; for example, the assassination of Louis Mountbatten, 1st Earl Mountbatten of Burma, assassination of Louis Mountbatten in August 1979 was carried out by IRA member Thomas McMahon (Irish republican), Thomas McMahon from Monaghan. An attempt by the two governments to resolve the conflict in Northern Ireland politically in 1972 through the Sunningdale Agreement failed due to opposition by hard-line factions in Northern Ireland. With no resolution to the conflict in sight, the Irish government established the New Ireland Forum in 1984 to look into solutions. While the British Prime Minister of the United Kingdom, UK Prime Minister Margaret Thatcher rejected the forum's proposals, it informed the British government's opinion and it is said to have given the Irish Taoiseach Garret FitzGerald a Mandate (politics), mandate during the negotiation of the 1985 Anglo-Irish Agreement, which was directed at resolving the conflict. The 1992 Downing Street Declaration further consolidated the views of the two Governments and the 1998 Good Friday Agreement eventually formed the basis for peace in the province. The Irish Department of Foreign Affairs established a "Reconciliation Fund" in 1982 to support organisations whose work tends to improve cross-community or North–South relations. Since 2006, the Minister for Foreign Affairs and Trade, Minister for Foreign Affairs has hosted an annual "Reconciliation Networking Forum" (sometimes called the "Reconciliation Forum"; not to be confused with the Forum for Peace and Reconciliation) in Dublin to which such groups are invited.


Brexit

There is Irish border question, a controversy about the impact that Britain's withdrawal from the European Union will have at the end of the transition period on the border between the Republic of Ireland and Northern Ireland, in particular the impact it may have on the economy and people of the island were customs or immigration checks to be put in place at the border. It was prioritized as one of the three most important areas to resolve in order to reach the Withdrawal Agreement, Agreement on the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union. The people of the UK voted to leave the European Union in a non-binding 2016 United Kingdom European Union membership referendum, referendum on 23 June 2016, an act which would effectively make the Republic of Ireland-Northern Ireland border an External border of the European Union, external EU border. Due to the lack of supporting legislation, all referendums in the UK are not legally binding, which was confirmed by a Supreme Court judge in November 2016. Nevertheless, the UK government chose to proceed with the departure from the European Union. All parties have stated that they want to avoid a hard border in Ireland particularly due to the sensitive nature of the border. The border issue is concerned by a protocol related to the withdrawal agreement, known as the Irish backstop, Protocol on Ireland and Northern Ireland.


Good Friday Agreement

The conflict in Northern Ireland, as well as dividing both Governments, paradoxically also led to increasingly closer co-operation and improved relations between Ireland and the United Kingdom. A 1981 meeting between the two governments established the Anglo-Irish Intergovernmental Council. This was further developed in 1985 under the Anglo-Irish Agreement whereby the two governments created the Anglo-Irish Intergovernmental Conference, under the Anglo-Irish Intergovernmental Council, as a regular forum for the two Governments to reach agreement on, "(i) political matters; (ii) security and related matters; (iii) legal matters, including the administration of justice; (iv) the promotion of cross-border co-operation." The Conference was "mainly concerned with Northern Ireland; but some of the matters under consideration will involve cooperative action in both parts of the island of Ireland, and possibly also in Great Britain." The Agreement also recommended the establishment of the Anglo-Irish Interparliamentary Body, a body where parliamentarians from the Houses of the Oireachtas (Ireland) and Houses of Parliament (United Kingdom) would regularly meet to share views and ideas. This was created in 1990 as the British–Irish Inter-Parliamentary Body. The Northern Ireland peace process culminated in the Good Friday Agreement of 1998 that further developed the institutions established under these Anglo-Irish Agreement. New institutions were established interlocking across "strands": * Strand I: an Assembly and Executive for Northern Ireland based on the D'Hondt method, D'Hondt system; * Strand II: a

"to promote the harmonious and mutually beneficial development of the totality of relationships among the peoples of these islands" *# a new British–Irish Intergovernmental Conference, established under the British–Irish Agreement, replaced the Anglo-Irish Intergovernmental Council and the Anglo-Irish Intergovernmental Conference. The scope of the British–Irish Intergovernmental Conference is broader that the original Conference, and is intended to "bring together the British and Irish Governments to promote bilateral co-operation at all levels on all matters of mutual interest within the competence of both Governments." The Conference also provides a joint institution for the government of Northern Ireland on non-devolved matters (or all matters when the Northern Ireland Assembly is suspended). However, the United Kingdom retains ultimate sovereignty over Northern Ireland. Representatives from Northern Ireland participate in the Conference when matters relating to Northern Ireland are concerned. The members of the British–Irish Council (sometimes called the ''Council of the Isles'') are representatives of the Irish and British Governments, the devolved administrations in Northern Ireland, Scotland and Wales, together with representatives of the Isle of Man and the Channel Islands. It meets regularly to discuss matters of mutual interest divided into work areas (such as energy, environment or housing) allocated to individual members to work and report on. The Anglo-Irish Interparliamentary Body developed independently over the same period, eventually becoming known as the British–Irish Parliamentary Assembly and including members from the devolved administrations of the UK and the Crown Dependencies. The development of these institutions was supported by acts such the visit of efforts by Mary Robinson (as President of Ireland) to the Queen Elizabeth II (Queen of the United Kingdom), an apology by Tony Blair (as Prime Minister of the United Kingdom) to Irish people for the failures of the British Government during the Great Famine (Ireland), Great Famine of 1845—1852 and the creation of the Island of Ireland Peace Park. A Queen Elizabeth II's visit to the Republic of Ireland, state visit of Queen Elizabeth II to Ireland in May 2011 – including the laying of a wreath at a memorial to Irish Republican Army, IRA fighters in the Anglo-Irish war – symbolically sealed the change in relationships between the two states following the transfer of police and justice powers to Northern Ireland. The visit came a century after her grandfather, King George V, was the last monarch of the United Kingdom to pay a state visit to Ireland in July 1911, while it was still part of the United Kingdom.

These participate in the shared institutions created between Ireland and the United Kingdom under the Good Friday Agreement. The United Kingdom and the Crown dependencies form what are called the ''British Islands''. The devolved administrations of the United Kingdom and the three Crown Dependencies also participate in the shared institutions established under the Good Friday Agreement. The British monarch was head of state of all of these states and countries of the archipelago from the Union of the Crowns in 1603 until their role in Ireland became ambiguous with the enactment of the Constitution of Ireland in 1937. The remaining functions of the monarch in Ireland were transferred to the President of Ireland, with coming into effect of the Republic of Ireland Act in 1949.


Academic perspectives

Several academic perspectives are important in the study and understanding of Ireland–United Kingdom relations. Important strands of scholarship include research on identity, especially Britishness and Irishness, and studies of the major political movements, such as separatism, Unionism in the United Kingdom, unionism and nationalism. The concept of post-nationalism is also contemporary trend in studies of history, culture and politics in the isles.


Co-operation

The British–Irish Intergovernmental Conference provides for co-operation between the Government of Ireland and the Government of the United Kingdom on all matters of mutual interest for which they have competence. Meetings take the form of Summit (meeting), summits between the Prime Minister of the United Kingdom and the Irish Taoiseach, on an "as required" basis. Otherwise, the two governments are represented by the appropriate ministers. In light of Ireland's particular interest in the governance of Northern Ireland, "regular and frequent" meetings co-chaired by the Irish Minister for Foreign Affairs and the UK Secretary of State for Northern Ireland, dealing with non-devolved matters to do with Northern Ireland and non-devolved all-Ireland issues, are required to take place under the establishing treaty. At these meetings, the Irish government may put forward views and proposals, however sovereignty over Northern Ireland remains with the United Kingdom. In all of the work of the Conference, "All decisions will be by agreement between both Governments [who] will make determined efforts to resolve disagreements between them." The Conference is supported by a standing secretariat located at Belfast, Northern Ireland, dealing with non-devolved matters affecting Northern Ireland.

, and meets in bi-annual summits and regular sectoral meetings. Summit meetings are attended by the heads of each administrations (e.g. the Prime Minister of the United Kingdom) whereas sectoral meetings are attended by the relevant Government minister, ministers form each administration. While the Council is made up of representatives from the executive of the various administrations in the region, it does not have executive power itself. Instead, its decisions, so far as they exist, are implemented separately by each administration on the basis of consensus. Given this – that the Council has no means to force its member administrations into implementing programmes of action – the Council has been dismissed as a "talking shop" and its current role appears to be one mainly of "information exchange and consultation". In addition to the Council, the British–Irish Parliamentary Assembly (BIPA) is composed of members of the legislative bodies in the United Kingdom, including the devolved legislatures, Republic of Ireland, Ireland, and the British crown dependency, Crown dependencies. It is the older of the two 'all-islands' institutions (BIC and BIPA) having been founded in 1990 as the British–Irish Inter-Parliamentary Body. Its purpose is to foster common understanding between elected representatives from these jurisdictions and, while having no legislative power, it conducts parliamentary activities such as receiving oral submissions, preparing reports and debating topical issues. The Assembly meets in plenary on a bi-annual basis, alternating in venue between Britain and Ireland, and maintains on-going work in committee. These institutions have been described as part of a confederation, confederal approach to the government of the British–Irish archipelago.

The Council is responsible for developing and executing policy in at least twelve areas of co-operation, of which: * at least six are executed separately in each jurisdiction * at least six are executed by an all-Ireland "implementation body" Further development of the role and function of the Council are possible "with the specific endorsement of the Northern Ireland Assembly and Oireachtas, subject to the extent of the competences and responsibility of the two Administrations." The North/South Ministerial Council and the Northern Ireland Assembly are defined in the Good Friday Agreement as being "mutually inter-dependent, and that one cannot successfully function without the other." Participation in the Council is a requisite for the operation of the Northern Ireland Assembly and participation in the Northern Ireland Executive. When devolution in Northern Ireland is suspended, the powers of the Northern Ireland Executive revert to the British–Irish Intergovernmental Conference. Meetings of the Council take the form of "regular and frequent" sectoral meetings between ministers from the

The Council has a permanent office located in Armagh,

, staffed by a standing secretariat. There is no joint parliamentary forum for the island of Ireland. However, under the Good Friday Agreement, the Oireachtas and Northern Ireland Assembly are asked to consider developing one. The Agreement also contains a suggestion for the creation of a consultative forum composed of members of civil society from Northern Ireland and the Republic of Ireland. Under the 2007, St. Andrew's Agreement, the Northern Ireland Executive agreed to support the establishment of a North/South Consultative Forum and to encourage parties in the Northern Ireland Assembly to support the creation of a North/South parliamentary forum.


Inter-regional relationships

Independent of the direct involvement of Government of the United Kingdom, the devolved administrations of the mainland United Kingdom and the Crown dependencies also have relationships and with Ireland. For example, the Irish and Welsh governments collaborate on various economic development projects through the Ireland Wales Programme, under the Interreg initiative of the European Union. The governments of Ireland and Scotland, together with the Northern Ireland Executive, also collaborated on the ISLES project under the aegis of the Special EU Programmes Body, set up under the Good Friday Agreement. The project was to facilitate the development of offshore renewable energy sources, such as Wind power, wind, Wave power, wave and Tidal power, tidal energy, and trade in renewable energy between

exists between the two states and the Crown Dependencies (which were never part of the EU, thus never obliged to join Schengen). The Common Travel Areas is not founded on any formal agreement between Ireland and the United Kingdom and is not provided for in legislation. Instead, it is an informal arrangement between the states. When the Schengen Area was incorporated into the European Union through the 1992 Amsterdam Treaty, the first formal recognition of the Common Travel areas was made though an annexed Protocol (treaty), protocol exempting their obligations to join. The UK's previous reluctance to join the Schengen Area when it was a member state, was mainly centred around concerns over loss of independent border controls, is usually cited as the reason for not joining. Britain argued that, for an island, frontier controls are a better and less intrusive way to prevent illegal immigration than other measures, such as identity cards, residence permits, and registration with the police. Consequent difficulties for Ireland, given its location and shared border with the UK (at which border points would have to be set up), would then make it very difficult for Ireland to join without the UK. Except for a period during and in the years after World War II, neither Ireland nor the UK have placed restrictions on travel between each other for citizens resident in each others states since Irish independence. Even during wartime, when Ireland remained neutral and the UK was a belligerent during World War II, the only significant restrictions on travel between the states were an Irish prohibition on the wearing of military uniforms by British citizens when in Irish territory and the instatement of passport controls between Great Britain and the island of Ireland. When Ireland declared itself a republic in 1949, thus making it impossible at the time to remain in the British Commonwealth, the British government Ireland Act 1949, legislated that even though the Republic of Ireland was no longer a British dominion, it would not be treated as a foreign country for the purposes of British law. Prior to post-World War II, both states mutually recognised each other's entry visas for foreigners. However, in 1952 changes to UK law rescinded this arrangement. In 2011, the first public agreement between the British and Irish governments concerning the maintenance of the Common Travel Area (CTA) was published. The agreement, which is non-binding, envisions increased co-ordination between Irish and British immigration arrangements and that, from July 2011 Ireland would recognise UK short terms visas on an 18-month pilot basis for nationals of 16 countries. The agreement also mooted the possibility of "Common Travel Area visit visa" including the possibility of a pilot project. The CTA applies only to Irish and British citizens. As such, residents of either state (or any of the Crown Dependencies) who do not hold one of those nationalities do not have an automatic right to enter Ireland from the UK, or vice versa, including over the land border. As a result of this, there was some controversy when the British government announced an electronic authorisation system for tourists to the UK, which would have meant non-citizen Irish residents, including EU nationals, would need to apply for an authorisation to cross the land border. This would include many who live near the border and cross regularly for leisure trips. In March 2024, the British government updated guidance to exempt residents of the republic from the scheme. There are no special arrangements for travel between the Common Travel Area and the Schengen Area and a Schengen visa entitle entry. However, citizens of the European Union, Norway, Iceland, Liechtenstein and Switzerland Visa policy in the European Union, may enter as a right using only their passports.


Citizenship and citizens rights

As a dominion of the
British Empire The British Empire comprised the dominions, Crown colony, colonies, protectorates, League of Nations mandate, mandates, and other Dependent territory, territories ruled or administered by the United Kingdom and its predecessor states. It bega ...
, citizens of the Irish Free State were regarded as British subjects in common with all other members of the Empire. Historically, as late as 1942, British jurisprudence was that Irish citizenship "did no more than confer ... a national character as an Irish citizen within the wider British nationality". Indeed, for some years, the British authorities refused to accept Irish passports. Starting from the basis of common citizenship, the two states to this day provide reciprocal recognition to each others' citizens. British and Irish citizens can avail themselves of public services (for example, health care and social welfare) in each other's jurisdictions on an equal basis and are entitled to the right of abode, with deportation only in the most exceptional of circumstances. They each have equal voting (and standing) rights in all elections held across the United Kingdom and Ireland (except for the election of the President of Ireland and referendums). Northern Ireland occupies a unique location in the citizenship of the islands, with Northern Ireland people being recognised under the Good Friday Agreement as (in general terms) simultaneously British and/or Irish citizens according to their choice. The interaction of overlapping citizens rights and laws has led to some cases of exploitation of loopholes to avoid the intention of the law. For example, the Twenty-seventh Amendment of the Constitution of Ireland was required to amend the potential for abuse of the rights of Irish citizenship to the right to abode in the United Kingdom. Before then, Irish citizenship was granted on the basis of ''jus soli'' (i.e. being born on the island of Ireland was reason in itself to be considered an Irish citizen). Chen case, In one case, a Chinese migrant to the UK, living in Wales on Great Britain, chose to give birth to a child in Northern Ireland, on the island of Ireland, to take advantage of Irish citizenship laws. Consequently, her child was born an Irish citizen by virtue of ''jus soli'' and so was entitled to permanent abode in the UK even though the mother did not have the right to visit the Republic of Ireland. The mother and father then claimed the right to stay in the United Kingdom by virtue of being the guardians of a citizen of the European Union who would be unable to look after himself should they be deported.


Energy

A Single Electricity Market, single wholesale electricity market exists on the island of Ireland since 2007. Work towards common arrangements for the transmission and distributions of natural gas, including a common retail market arrangements by 2014, on the island are also underway. In 2004, a natural gas interconnection agreement was signed between the United Kingdom and Ireland, linking Ireland with Scotland via the Isle of Man. In 2011, the members of the British–Irish Council agreed an "All Islands Approach (AIA)" to electricity grid infrastructure and have launched a programme of joint work examining renewable energy trading as well as interconnection and market integration.


Shared bodies

The United Kingdom and Ireland share a number of civic bodies such as the Royal National Lifeboat Institution, that provides sea-rescue across the islands of Great Britain and Ireland. The three General lighthouse authority, lighthouse authorities in the archipelago (the Northern Lighthouse Board, Trinity House, Trinity House Lighthouse Service and the Commissioners of Irish Lights) are funded by a single General Lighthouse Fund managed by the UK Department for Transport and paid for by light dues levied on ships calling at British and Irish ports. While this broad arrangement will continue, the total cost of the Commissioners of Irish Lights' work in Ireland (not Northern Ireland) will be met from income raised domestically as from 2015—16.


Military cooperation

The Republic of Ireland and the United Kingdom normalised military cooperation with the signing of a Memorandum of Understanding between the Irish Department of Defence (Ireland), Department of Defence and the British Ministry of Defence (United Kingdom), Ministry of Defence in January 2015. Historically, Ireland has maintained a policy of strict military neutrality since the foundation of the state. As a result, Ireland has never joined the UK as an active ally, during any modern conflict.


Political movements

An important political movement in several countries in the Isles is British unionism, an ideology favouring the continued union of the United Kingdom. It is most prevalent in Unionism in Scotland, Scotland, Wales, England, and Unionism in Ireland, Northern Ireland. British unionism has close ties to British nationalism. Another movement is Loyalism#Modern loyalists in Great Britain and Ireland, Loyalism, which manifests itself as loyalism to the

. The converse of unionism, nationalism, is also an important factor for politics in the Isles. Nationalism can take the form of Welsh nationalism, Cornish nationalism, English nationalism, Scottish nationalism, Ulster nationalism, Northern Ireland nationalism, Irish republicanism in Northern Ireland, Irish nationalism in Northern Ireland or independence movements in the Isle of Man or Channel Islands. Several Irish parties are organised on both sides of the Irish border. In recent years,

Immigration and emigration

Irish migration to Great Britain is an important factor in the politics and labour markets of the Isles. Irish people have been the largest ethnic minority group in Britain for centuries, regularly migrating across the Irish Sea. From the earliest recorded history to the present, there has been a continuous movement of people between the islands of Ireland and Great Britain due to their proximity. This tide has ebbed and flowed in response to politics, economics and social conditions of both places. At the 2011 census, there were 869,000 Irish-born residents in the United Kingdom. As of 2013, the Britons represent the largest immigrant minority of European origin in the Republic of Ireland.

Media

The United Kingdom and Ireland have separate media, although British television, newspapers and magazines are widely available in Ireland, giving people in Ireland a high level of familiarity with cultural matters in the United Kingdom. Republic of Ireland newspapers and magazines are commonly available in Northern Ireland, and the two main Irish broadsheets, ''The Irish Times'' and the ''Irish Independent'' are frequently available to the diaspora in Great Britain. Certain reality TV shows have embraced the whole of the islands, for example ''The X Factor (UK), The X Factor'', seasons 3, 4 and 7 of which featured auditions in Dublin, were open to voters in the Republic, while the show previously known as ''Britain's Next Top Model'' became ''Britain and Ireland's Next Top Model'' in 2011. Ireland and the United Kingdom have agreed to a deal on the digital broadcast of BBC Northern Ireland and Channel 4 into the Republic of Ireland and of RTÉ and TG4 into Northern Ireland. Tara Television, which broadcast Irish programming into Great Britain, was wound up in 2002. A replacement, under the working title of ''RTÉ International'', was postponed due to financial conditions. Instead, RTÉ Player provides a subset of programming for audiences outside Ireland. Some cultural events are organised for the island group as a whole. For example, the Costa Book Awards are awarded to authors resident in the UK or Ireland. The Booker Prize is awarded to authors from the Commonwealth of Nations and Ireland. The Mercury Music Prize is handed out every year to the best album from an Irish or British musician or group.


Sport

The British and Irish Lions is a team made up of players from England national rugby union team, England, Ireland national rugby union team, Ireland, Scotland national rugby union team, Scotland and Wales national rugby union team, Wales that undertakes tours of the southern hemisphere rugby playing nations every four years. The Ryder Cup in golf was originally played between a United States team and a team representing Great Britain and Ireland. From 1979 onwards this was expanded to include the whole of Europe. In 2012, the Olympic torch visited Dublin on 2012 Summer Olympics torch relay, a tour of the UK ahead of the 2012 Olympic Games in London. Dublin was the only place outside of the UK (apart from the traditional lighting ceremony in Greece) that the torch visited. UK Secretary of State for Culture, Olympics, Media and Sport, Jeremy Hunt (politician), Jeremy Hunt, said: "The Republic of Ireland is the only country outside the UK to be visited by the torch and rightly so, given the unique and deep ties between Ireland and the UK."


Economic relations

Due to the linguistic, cultural and legal (both as common law countries) similarities between the UK and Ireland, many businesses in both countries have operations in each other country. Both countries have each other as their biggest business partner, and both in the same trade organisations include the
European Union The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The u ...
and World Trade Organization. Examples of notable British companies that have an Irish operations come as diverse as the supermarket chain Tesco (Tesco Ireland), the department store Marks & Spencer, telecoms company BT plc, BT (BT Ireland) and electric company SSE plc (Airtricity). Notable Irish companies that work in the UK includes the airline Ryanair, fashion retailer Primark (founded in Dublin but now owned by Associated British Foods), food processor Kerry Group, dairy company Ornua, Beer in Ireland, Irish Stout Brewery Guinness (owned by Diageo) and electric management company ESB Group, ESB. Due to the closeness, some businesses often treat both countries of trade, finance and marketing as a single unit as quoting for "UK and Ireland" rather than two separate countries. British Prime Minister Keir Starmer visited Dublin, signalling improved relations between Britain and Ireland. Both he and Irish Prime Minister Simon Harris emphasised moving from post-Brexit "friction back to friendship," aiming to strengthen diplomatic and trade ties.


Trade agreements

After both nations' bids to join the European Economic Community were rejected, Ireland and the UK signed the Free trade agreements of the United Kingdom#Obsolete agreements, Ireland–UK Free Trade Area agreement on 19 December 1965. The bilateral free trade area was legally in force from 1 July 1966 until 1 January 1973. Both countries joined the European Economic Community on 1 January 1973. The European Economic Community was incorporated into the European Union on the 1 November 1993. Following the result of the 2016 United Kingdom European Union membership referendum, Brexit referendum, the UK invoked United Kingdom invocation of Article 50 of the Treaty on European Union, Article 50 in March 2017. The UK Brexit withdrawal agreement, officially withdrew from the EU on the 1 January 2021. Trade between the Free trade agreements of the United Kingdom, United Kingdom and Ireland is governed by the EU–UK Trade and Cooperation Agreement since 1 January 2021.
