The Labour Party, led by Neil Kinnock, was slowly moving towards a more centrist policy platform. The main aim of the Labour Party was simply to re-establish itself as the main progressive centre-left alternative to the Conservatives, after the rise of the Social Democratic Party (SDP) forced Labour onto the defensive. Indeed, the Labour Party succeeded in doing so at this general election. The Alliance between the SDP and the Liberal Party was renewed but co-leaders David Owen and David Steel could not agree whether to support either major party in the event of a hung parliament.
