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.)

resigned the Labour whip and another, Tom Bradley, announced he would not contest his seat again as a Labour candidate. These moves were reported to be a clear move towards formally creating a new centre party. Former Labour Party deputy leader, Baron George-Brown also announced his membership of the Council for Social Democracy. Possible names for the party included ones similar to Labour, such as "Democratic Labour", "Progressive Labour" and "New Labour". Other, simpler names like "Democratic", "Radical", "Progressive" and "Centre" were also all mentioned as possible names for the new party. However, eventually a consensus emerged for the "Social Democratic" name as it helped to distinguish the party from Labour, and had been widely used to refer to the group in the media. 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). Twenty-eight Labour MPs eventually joined the new party, along with one member of the Conservative Party,

caused some embarrassment, however, by publicly stating that the SDP "should be strangled at birth". During an era of widescale unemployment and public disillusionment with the two main parties—Labour and the Conservatives—the Alliance achieved considerable success at parliamentary by-elections. At one point in late-1981, the Alliance had an opinion poll rating of over 50%. That same year, David Steel addressed 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.

. On 13 June, Jenkins stood down and of the six SDP MPs elected in 1983, only Owen stood for leader of the Party. Subsequently he became leader without any contest a week later. Owen 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

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.

Merger, disestablishment and splits

Following 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. Owen resigned as leader and was replaced by

Structure and organisation

led seats. The Party had three key leading organs. The first was the National Committee which was the executive body of the party, the second was the Council for Social Democracy (CSD), and the last was Policy Committee which set the policy of the SDP.


Policy Committee

The Policy Committee was a sub-committee of the National Committee, and was the most powerful body of the SDP. Membership of the Policy Committee was composed of: * Leader of the SDP * President * 10 MPs sitting on the National Committee * 9 members elected by the National Committee

Council for Social Democracy

The Council for Social Democracy was the largest of the three organs. Totaling approximately 400 elected members, it was often nicknamed as the "Parliament of the Party". The constitution of the SDP stipulated that the CSD met thrice yearly, and that it be chaired by the President.


Election results


House of Commons

As of the dissolution of parliament before the 1983 election, the SDP had 32 MPs. In the 1983 election, only 4 SDP MPs gained through defections were held. Between the 1983–1987 elections, the SDP won two by-elections taking their total to 8 at dissolution, however neither were re-elected. They are not counted in the seats gained or lost section.
