The Churchill war ministry was a Conservative-led coalition government in the United Kingdom, which lasted for most of World War II. It was led by Winston Churchill, as Prime Minister of the United Kingdom. Formed in 1940, within a year of the war's outbreak, it lasted until 23 May 1945, shortly after the defeat of Nazi Germany, when Churchill resigned and an election was called.
The war ministry was followed by the Churchill caretaker ministry which in turn lasted until 26 July 1945 when the results of the general election brought Labour into government, led by Clement Attlee.
