Lionized for helping lead the Allies to victory in World War II, Winston Churchill was widely expected to run away with a win in Britain's first postwar elections in 1945. Instead, he proved unable to set a clear peacetime direction for his Conservative Party. Britons, taken with the Labour Party's promises of a welfare state, full employment and National Health Service, chose Clement Attlee in a landslide. It took six years and another loss, in 1950 before Churchill was returned to office in 1951. He served as Prime Minister until 1955, when he resigned at age 80 due to failing health.
