Timeline of Winston Churchill's first premiership

The following is a timeline of the first premiership of Winston Churchill, who was the Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. Churchill served as the Prime Minister of the United Kingdom during the bulk of World War II. His speeches and radio broadcasts helped inspire British resistance, especially during the difficult days of 1940–41 when the British Commonwealth and Empire stood almost alone in its active opposition to Nazi Germany. He led Britain as Prime Minister until victory over Nazi Germany had been secured.

After the Conservative Party lost the 1945 election, Churchill became Leader of the Opposition to the Labour Government. He would go on to be re-elected as Prime Minister in 1951.
