The four left the Labour Party as a result of the January 1981 Wembley conference which committed the party to unilateral nuclear disarmament and withdrawal from the European Economic Community. They also believed that Labour had become too left-wing, and had been infiltrated at constituency party level by Militant tendency whose views and behaviour they considered to be at odds with the Parliamentary Labour Party and Labour voters. Shortly after its formation, the SDP formed a political and electoral alliance with the Liberal Party, the

Origins

The origin of the party can be traced back to the ideological divisions in the Labour Party in the 1950s (with its forerunner being the Campaign for Democratic Socialism established to support the Gaitskellites), but publicly lies in the 1979

. There were long-running claims of corruption and administrative decay within Labour at local level (the North East of England was to become a cause célèbre), and concerns that experienced and able Labour MPs could be deselected (i.e., lose the Labour Party nomination) by those wanting to put into a safe seat their friends, family or members of their own Labour faction. In some areas, the Militant tendency were held to be systematically targeting weak local party branches in safe seat areas in order to have their own candidates selected, and thus become MPs.

In Taverne's case, he had been fighting efforts by the Lincoln Constituency Labour Party to deselect him largely over his support for British membership of the European Communities. In October 1972 he resigned his seat to force a

in which he fought as a Democratic Labour candidate against the official party candidate. Taverne won by an unexpectedly large margin.John Ramsden and Richard Jay, "Lincoln: Background to Taverne's Triumph" in "By-elections in British Politics", Macmillan, 1973, pp. 264-315. He founded the short lived Campaign for Social Democracy (CFSD) thereafter, and wrote a book about events surrounding the by-election called ''The Future of the Left – Lincoln and After'' (1972). But the CFSD failed to gain nationwide support, and Taverne lost the seat at the October 1974 general election. Some independent Social Democrats contested the October 1974 and 1979 general elections, but none were elected. Taverne's Lincoln by-election campaign was also helped to a lesser degree by problems with the

His suggestion during the by-election that murderers should have razor blades left in their cells so they could decently commit suicide resulted in him being nicknamed "Old Razor Blades" during the campaign. This, combined with considerable Conservative grassroots disquiet over the Monday Club's links to the National Front, persuaded some Conservative voters to switch to Taverne in protest as much as tactically to ensure Labour suffered an embarrassing loss. (Guinness had been elected as Chairman specifically to eradicate such links.)

, Shirley Williams and Bill Rodgers, known collectively as the " Gang of Four") launched the Council for Social Democracy, after outlining their policies in what became known as the Limehouse Declaration. In March it was renamed the Social Democratic Party. The "Gang of Four" were centrists, who defected from the Labour Party due to what they perceived to be the influence of the Militant tendency and the " hard left" within the party. Thirteen Labour MPs initially declared support for the Council for Social Democracy. On 20 February 1981, three of these Tom Ellis, Richard Crawshaw and

would use to successfully promote the Labour Party more than a decade later) but eventually "Social Democratic" was settled on because the "Gang of Four" consciously wanted to mould the philosophy and ideology of the new party on the social democracy practised on mainland Europe. The opening statement of principles contained in the preamble of the party's constitution stated that: "The SDP exists to create and defend an open, classless and more equal society which rejects prejudices based upon sex, race, colour or religion". The constitution set out the establishment of a "Council for Social Democracy" (CSD) which was, in effect, the party's standing conference. Each area party was entitled to elect delegates to the CSD. A number of internal groups flourished within the new party, the most notable of which was the Tawney Society (mirroring the function of the Fabian Society within the Labour Party).

. Although the SDP was seen as being largely a breakaway from the right-wing of the Labour Party, an internal party survey found that 60% of its members had not belonged to a political party before, with 25% being drawn from Labour, 10% from the Conservatives and 5% from the Liberals. The party enjoyed a considerable honeymoon period with the press, who made much mileage out of their quirk for proffering claret at their functions. Claret is an "agreeable" wine, and a metaphor for the party's harmonious internal relations compared to those of the strife-torn Labour Party of the period. The policies of the SDP emphasised a middle position between perceived extremes of Thatcherism and the Labour Party. Its constitution argued for "the fostering of a strong public sector and a strong private sector without frequent frontier changes". The SDP favoured some

At the party's first electoral contest, Jenkins narrowly failed to win a by-election at Warrington in July 1981, describing it as his "first defeat, but by far my greatest victory".

Ultimately, the SDP's Jenkins was elected. A leadership election was held later in the year, Jenkins beating Owen in the ballot to become the first leader of the new party. Later in the year, Shirley Williams defeated Bill Rodgers in the ballot to become SDP president.

caused some embarrassment, however, by publicly stating that the SDP "should be strangled at birth". During an era of public disillusionment with the two main parties – Labour and the Conservatives – and widescale unemployment, the Alliance achieved considerable success at parliamentary by-elections. At one point in late-1981, the party had an opinion poll rating of over 50%. Also in 1981, David Steel was able to address the Liberal Party conference with the phrase "Go back to your constituencies, and prepare for government!" In early-1982, after public disagreements over who could fight which seats in the forthcoming election, the poll rating dipped, but the party remained ahead of both Labour and the Conservatives. However, following the outbreak of the

between 1974 and 1979), took over as SDP leader after the 1983 general election. He was more sceptical about close relations with the Liberals than his predecessor Roy Jenkins, and favoured retaining the party's distinct identity. Owen's influence ensured that proposals for a merger between the two parties were shelved after a lengthy debate at the 1983 SDP conference. During the 1983–87 parliament, some SDP members started to become unsettled at what appeared to be the increasingly right-wing course taken by SDP leader David Owen. This resulted in some members launching the Limehouse Group in an attempt to keep the party on the centre-left course that was first propounded in the Limehouse Declaration. Two more SDP MPs were elected at by-elections during the 1983–87 parliament, but at the 1987 general election, the Alliance's share of the vote fell to 23%, and the SDP's parliamentary party was reduced from eight members to five. Roy Jenkins was among those who lost their seats. Mike Hancock had won a by-election at Portsmouth South in 1984 from the Conservatives which was lost in 1987, but

, who had won the bitterly contested Greenwich by-election in February 1987 from Labour; managed to hold on at the general election in June that year. From the outset, the formation of the Alliance had raised questions as to whether it would lead to a merged party, or the two parties were destined to compete with each other. This in turn led to grassroots tensions in some areas between Liberal and SDP branches that impaired their ability to mount joint campaigns successfully. Such cross-party feuding was part of the reason for Jenkins losing his Glasgow Hillhead seat to

Merger, disestablishment and splits

After the disappointment of 1987, Steel proposed a formal merger of the two parties. Jenkins and Steel had believed this to be eventually inevitable after the party failed to break through at the 1983 election. The proposal, also supported by Williams and Rodgers, was fiercely opposed by Owen, who argued that such a merger would not be accepted by the electorate, and would not reverse their declining share of the vote. Jenkins denied that a merger had been his original intent. But the majority of the SDP's membership (along with those of the Liberals) voted in favour of the union.
