Clement Richard Attlee, 1st Earl Attlee, KG, OM, CH, PC, FRS was a British politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955. He was Deputy Prime Minister during the wartime coalition government under Winston Churchill, and served twice as Leader of the Opposition from 1935 to 1940 and from 1951 to 1955.
Attlee was born into an upper-middle-class family, the son of a wealthy London solicitor. After attending the public school Haileybury College and the University of Oxford, he practised as a barrister. The volunteer work he carried out in London's East End exposed him to poverty and his political views shifted leftwards thereafter. He joined the Independent Labour Party, gave up his legal career, and began lecturing at the London School of Economics. His work was interrupted by service as an officer in the First World War. In 1919, he became mayor of Stepney and in 1922 was elected Member of Parliament for Limehouse. Attlee served in the first Labour minority government led by Ramsay MacDonald in 1924, and then joined the Cabinet during MacDonald's second minority.
