full_context: Document 1: Clement Attlee: Clement Richard Attlee, 1st Earl Attlee, {'1': ", '2': ", '3': ", '4': "} (3 January 1883 – 8 October 1967) was a British Labour politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955. In 1940, Attlee took Labour into the wartime coalition government and served under Winston Churchill, becoming the first person to hold the office of Deputy Prime Minister of the United Kingdom. He went on to lead the Labour Party to an unexpected landslide victory at the 1945 general election; forming the first Labour majority government, and a mandate to implement its postwar reforms. The 12.0% national swing from the Conservatives to Labour was unprecedented at that time and remains the largest ever achieved by any party at a general election in British electoral history. He was re-elected with a narrow majority at the 1950 general election. In the following year, Attlee called a snap general election, hoping to increase his parliamentary majority. However, he was narrowly defeated by the Conservatives under the leadership of Winston Churchill; despite winning the most votes of any political party in any general election in British political history until the Conservative Party's fourth consecutive victory in 1992. Attlee remains the longest-ever serving Leader of the Labour Party.
Document 2: United Kingdom general election, 1931: The United Kingdom general election held on Tuesday 27 October 1931 saw a landslide election victory for the National Government which had been formed two months previously after the collapse of the previous Labour government. The bulk of the National Government's support came from the Conservative Party, and the Conservatives won 470 seats. The Labour party suffered its greatest defeat, losing four out of five seats compared with the previous election. The Liberal Party, split into three factions, continued to shrink and the Liberal National faction never reunited. Ivor Bulmer-Thomas said the results "were the most astonishing in the history of the British party system". It was the last election where one party (the Conservatives) received an absolute majority of the votes cast and the last UK general election not to take place on a Thursday.
Document 3: Later life of Winston Churchill: The later life of Winston Churchill documents the life of the British statesman from the end of World War II and his second term as Prime Minister of the United Kingdom, until his subsequent death and funeral in 1965. After the end of the war Churchill had to step down as Prime Minister of the United Kingdom because the Conservative Party lost the 1945 election. For six years he was to serve as the Leader of the Opposition. During these years Churchill continued to influence world affairs; in 1946 he gave his Iron Curtain speech which spoke of the expansionist policies of the USSR and the creation of the Eastern Bloc; Churchill also argued strongly for British independence from the European Coal and Steel Community (which he saw as a Franco-German project as Britain still had an empire). In the General Election of 1951 Labour was defeated and Churchill became Prime Minister for a second time. Churchill continued to lead Britain but was to suffer increasingly from health problems. Aware that he was slowing down both physically and mentally he resigned from the Cabinet in 1955. However he continued to sit as an MP for Woodford until he retired from politics in 1964. Churchill died on 24 January 1965 and was granted the honour of a state funeral. He was buried in his family plot in St Martin's Church, Bladon near to where he was born at Blenheim Palace.
