The Labour Party is a centre-left political party in the United Kingdom. It has been described as a broad church, containing a diversity of ideological trends from strongly socialist, to more moderately social democratic. Founded in 1900, the Labour Party overtook the Liberal Party in general elections during the early 1920s and formed minority governments under Ramsay MacDonald in 1924 and 1929–31. The party was in a wartime coalition from 1940 to 1945, after which it formed a majority government under Clement Attlee. Labour was also in government from 1964 to 1970 under Harold Wilson and from 1974 to 1979, first under Wilson and then James Callaghan.
The Labour Party was last in national government between 1997 and 2010 under Tony Blair and Gordon Brown, beginning with a landslide majority of 179, reduced to 167 in 2001 and 66 in 2005. Having won 258 seats in the 2010 general election, the party currently forms the Official Opposition in the Parliament of the United Kingdom. Labour has a minority government in the Welsh Assembly, is the main opposition party in the Scottish Parliament and has 13 MEPs in the European Parliament, sitting in the Socialists and Democrats group. The Labour Party is a full member of the Party of European Socialists andProgressive Alliance, and continues to hold observer status in the Socialist International. The current leader of the party is Ed Miliband MP.
