The Churchill war ministry was the United Kingdom's coalition government for most of the Second World War from 10 May 1940 to 23 May 1945. It was led by Winston Churchill, who was appointed prime minister of the United Kingdom by King George VI following the resignation of Neville Chamberlain in the aftermath of the Norway Debate.

The 1945 United Kingdom general election was a national election held on Thursday 5 July 1945, but polling in some constituencies was delayed by some days, and the counting of votes was delayed until 26 July to provide time for overseas votes to be brought to Britain. The governing Conservative Party sought to maintain its position in Parliament but faced challenges from public opinion about the future of the United Kingdom in the post-war period. Prime Minister Winston Churchill proposed to call for a general election in Parliament, which passed with a majority vote less than two months after the conclusion of the Second World War in Europe.
