and has a coastline.
The length of coastline of Great Britain plus its principal islands is about long, with the coastline of the main island Great Britain being of that,

The prevailing wind is from the southwest and bears frequent spells of mild and wet weather from the Atlantic Ocean,
although the eastern parts are mostly sheltered from this wind. Since the majority of the rain falls over the western regions, the eastern parts are the driest. Atlantic currents, warmed by the Gulf Stream, bring mild winters, especially in the west where winters are wet and even more so over high ground. Summers are warmest in the southeast of England and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills.

Administrative divisions

The geographical division of the United Kingdom into Counties of the United Kingdom, counties or Shire, shires began in England and Scotland in the early Middle Ages, and was completed throughout Great Britain and Ireland by the early modern period. Modern local government by elected councils, partly based on the ancient counties, was established by separate Acts of Parliament: in England and Wales Local Government Act 1888, in 1888, Scotland Local Government (Scotland) Act 1889, in 1889 and Ireland Local Government (Ireland) Act 1898, in 1898, meaning there is no consistent system of administrative or geographic demarcation across the UK, and

[; ] Until the 19th century there was little change to those arrangements, but there has since been a constant evolution of role and function.
Local government in England is complex, with the distribution of functions varying according to local arrangements. The upper-tier subdivisions of England are the nine Regions of England, regions, used primarily for statistical purposes. One of the regions, Greater London Authority, Greater London, has had a directly elected assembly and mayor since 2000 following popular support for the proposal in a 1998 Greater London Authority referendum, 1998 referendum.
Local government in Scotland is divided into subdivisions of Scotland, 32 council areas with a wide variation in size and population. The cities of Glasgow, Edinburgh, Aberdeen and Dundee are separate council areas, as is the Politics of the Highland council area, Highland Council, which includes a third of Scotland's area but only just over 200,000 people. Local councils are made up of elected councillors, of whom there are 1,223.
Local government in Wales consists of 22 Unitary authority, unitary authorities, each led by a leader and cabinet elected by the council itself. These include the cities of Cardiff, Swansea and Newport, Wales, Newport, which are unitary authorities in their own right.
Elections are held every four years under the first-past-the-post system.
Local government in Northern Ireland since 1973 has been organised into 26 district councils, each elected by single transferable vote. Their powers are limited to services such as waste collection, dog control, and maintaining parks and cemeteries.
In 2008 the executive agreed on proposals to create 11 new councils to replace the existing system.
Devolution
In the United Kingdom a process of devolution has transferred various powers from the UK Government to three of the four UK countries—Scotland, Northern Ireland and Wales—as well as to the regions of England, which since 1999 have their own governments and parliaments which control various devolved matters.
[; ] These powers vary and have been moved to the Scottish Government, the Welsh Government, the Northern Ireland Executive and in England, the Greater London Authority, Combined authorities and combined county authorities, Combined Authorities and Combined authorities and combined county authorities, Combined County Authorities. Amongst the devolved parliaments across the United Kingdom, the Scottish Parliament has the most extensive responsibilities for Devolved, reserved and excepted matters, devolved powers, and has been described as "one of the most powerful devolved parliaments in the world".
The UK has an uncodified constitution and constitutional matters are not amongst the powers that have been devolved. Under the doctrine of Parliamentary sovereignty in the United Kingdom, parliamentary sovereignty, the UK Parliament could, in theory, therefore, abolish the Scottish Parliament, Senedd or Northern Ireland Assembly. Though in the Scotland Act 2016 and the Wales Act 2017 it states that the Scottish Government and the Welsh Government "are a permanent part of the United Kingdom's constitutional arrangements".
In practice it would be politically difficult for the UK Parliament to abolish devolution to the Scottish Parliament and the Senedd, because these institutions were created by referenda. The political constraints placed upon the UK Parliament's power to interfere with devolution in Northern Ireland are greater still, because devolution in Northern Ireland rests upon an international agreement with the Government of Ireland. The UK Parliament restricts the three devolved parliaments' legislative powers in economic policy matters through United Kingdom Internal Market Act 2020, an act passed in 2020.
England
Unlike Scotland, Northern Ireland and Wales, England does not have a separate devolved government or national parliament, rather a process of devolution of powers from the central government to local authorities has taken place, first in 1998. The Greater London Authority (GLA) was set up following a 1998 Greater London Authority referendum, referendum in 1998. Colloquially known as City Hall, it is the devolved regional government body for Greater London. It consists of two political branches: an Mayor of London, Executive Mayor and the London Assembly, which serves as a check and balance on the Mayor.
A Combined authorities and combined county authorities, Combined Authority (CA) is a type of local government institution introduced in England outside Greater London by the Local Democracy, Economic Development and Construction Act 2009. CAs allow a group of local authorities to pool appropriate responsibility and receive certain devolved functions from central government in order to deliver transport and economic policy more effectively over a wider area.
A Combined authorities and combined county authorities, Combined County Authority (CCA) is a similar type of local-government institution introduced in England outside Greater London by the Levelling-up and Regeneration Act 2023, but may only be formed by upper-tier authorities: county councils and Unitary authority, unitary authorities.
Scotland
Since 1999 Scotland has had a devolved national government and parliament with wide-ranging powers over any matter that has not been specifically Reserved and excepted matters, reserved to the UK Parliament.

Local government in Scotland is divided into subdivisions of Scotland, 32 council areas with a wide variation in size and population. Local councils are made up of elected councillors, of whom there are 1,223.
The Scottish Parliament is separate from the Scottish Government. It is made up of 129 elected members of the Scottish Parliament (MSPs).

Wales
Since 1999 Wales has had a devolved national government and legislature, known as the Senedd. Elections to the Senedd use the additional member system. It has more limited powers than those devolved to Scotland. The Senedd can legislate on any matter not specifically reserved to the UK Parliament by Acts of Senedd Cymru. The Welsh Government is currently a Welsh Labour minority government led by the First Minister of Wales, first minister, Eluned Morgan. Local government in Wales consists of 22 unitary authorities, each led by a leader and cabinet elected by the council itself.
Northern Ireland

The Agreement was 1998 Northern Ireland Good Friday Agreement referendum, confirmed by referendum and implemented later that year.
