British political party whose historic links with trade unions have led it to promote an active role for the state in the creation of economic prosperity and the provision of social services.
In opposition to the Conservative Party , it has been Britain's major democratic socialist party since the early 20th century. In 1900 the Trades Union Congress and the Independent Labour Party (founded 1893) established the Labour Representation Committee, which took the name Labour Party in 1906. In 1918 it became a socialist party with a democratic constitution, and by 1922 it had supplanted the Liberal Party as the official opposition party. In 1924 James Ramsay MacDonald formed the first Labour government, with Liberal support. The party was out of power from 1935 until a spectacular recovery in 1945 brought in Clement R. Attlee 's government (until 1951), which introduced a system of social welfare, including a national health service , and extensive nationalization of industry. Labour regained power under Harold Wilson (196470) and later James Callaghan (197479), but it foundered because of economic problems and worsening relations with its trade-union allies. In 1983 Michael Foot 's radical program resulted in a massive Labour defeat. Neil Kinnock moved the party toward the centre, but only in 1997 did Tony Blair and his "New Labour" agenda succeed in returning Labour to power.
