Dates of existence
The Social Democratic Party (SDP) was a centrist political party in the United Kingdom.
The SDP was founded on 26 March 1981 by four senior Labour Party moderates, dubbed the 'Gang of Four': Roy Jenkins, David Owen, Bill Rodgers and Shirley Williams, who issued the Limehouse Declaration. Owen and Rodgers were sitting Labour Members of Parliament (MPs); Jenkins had left Parliament in 1977 to serve as President of the European Commission, while Williams had lost her seat in the 1979 general election. 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 Trotskyist factions whose views and behaviour they considered to be at odds with the Parliamentary Labour Party and Labour voters.
