The electoral onslaught shook Labour but left them still in office. It took what Churchill called “one more heave” to defeat them in a second election, in October 1951. Churchill again took a vigorous lead in the campaign. He pressed the government particularly hard on its handling of the crisis caused by Iran’s nationalization of British oil companies and in return had to withstand charges of warmongering. The Conservatives were returned with a narrow majority of 17, and Churchill became prime minister for the second time. He formed a government in which the more liberal Conservatives predominated, though the Liberal Party itself declined Churchill’s suggestion of office. A prominent figure in the government was R.A. Butler, the progressive-minded chancellor of the Exchequer. Anthony Eden was foreign secretary. Some notable Churchillians were included, among them Lord Cherwell, who, as paymaster general, was principal scientific adviser with special responsibilities for atomic research and development.
While largely unstated, one of Churchill’s major concerns was limiting Soviet territorial gains in Europe. Having an eye toward the postwar world, he did not want Stalin in control of formerly democratic nations. However, geopolitics required further cooperation with his unlikely ally, and Churchill met Roosevelt for the last time in Stalin’s domain—Yalta in the Crimea, in February 1945. Victory in Europe was visible by then, though with more hard fighting to come in the Pacific. Roosevelt’s premature death in April ended the original Big Three.
