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 by King George VI following the resignation of Neville Chamberlain in the aftermath of the Norway Debate. At the outset, Churchill formed a five-man war cabinet which included Chamberlain as Lord President of the Council, Clement Attlee as Lord Privy Seal and later as Deputy Prime Minister, Viscount Halifax as Foreign Secretary and Arthur Greenwood as a minister without portfolio. Although the original war cabinet was limited to five members, in practice they were augmented by the service chiefs and ministers who attended the majority of meetings. The cabinet changed in size and membership as the war progressed but there were significant additions later in 1940 when it was increased to eight after Churchill, Attlee and Greenwood were joined by Ernest Bevin as Minister of Labour and National Service; Anthony Eden as Foreign Secretary – replacing Halifax, who was sent to Washington D.C. as ambassador to the United States; Lord Beaverbrook as Minister of Aircraft Production; Sir Kingsley Wood as Chancellor of the Exchequer and Sir John Anderson as Lord President of the Council – replacing Chamberlain who died in November (Anderson later became Chancellor after Wood's death in September 1943). The coalition was dissolved in May 1945, following the final defeat of Germany, when the Labour Party decided to withdraw in order to prepare for a general election. Churchill, who was the leader of the Conservative Party, was asked by the King to form a new, essentially Conservative, government. It was known as the Churchill caretaker ministry and managed the country's affairs until completion of the general election on 26 July that year. Background The 1935 general election had resulted in a Conservative victory with a substantial majority and Stanley Baldwin became Prime Minister. In May 1937, Baldwin retired and was succeeded by Neville Chamberlain who continued Baldwin's foreign policy of appeasement in the face of German, Italian and Japanese aggression. Having signed the Munich Agreement with Hitler in 1938, Chamberlain became alarmed by the dictator's continuing aggression and, in March 1939, signed the Anglo-Polish military alliance which supposedly guaranteed British support for Poland if attacked. Chamberlain issued the declaration of war against Germany on 3 September 1939 and formed a war cabinet
