See also: Later life of Winston Churchill. The Conservative Party returned to power in the United Kingdom after winning the 1951 general election following six years in opposition. This was the first majority Conservative government formed since Stanley Baldwin's 1924–1929 ministry. Winston Churchill became prime minister for a second time. Churchill's government had several prominent figures and up-and-coming stars. Rab Butler was appointed as Chancellor of the Exchequer while Sir Anthony Eden returned as Foreign Secretary. The noted Scottish lawyer Sir David Maxwell Fyfe, who had gained fame as a prosecutor at the Nuremberg Trials, became Home Secretary. He remained in this post until 1954, when he was ennobled as Viscount Kilmuir and appointed Lord Chancellor. Future Conservative Prime Minister Harold Macmillan achieved his first major Cabinet position when he was made Minister of Defence in 1954.
Gwilym Lloyd George, younger son of former Liberal Party leader and Prime Minister David Lloyd George, replaced Sir David Maxwell Fyfe as Home Secretary in 1954. Florence Horsbrugh became the first woman to hold a Cabinet post in a Conservative government when she was appointed Minister of Education in 1951. Several figures who were later to achieve high offices held their first governmental posts. These included: future Conservative Prime Minister Edward Heath, future Chancellors of the Exchequer Reginald Maudling, Peter Thorneycroft and Iain Macleod and future Foreign Secretary Lord Carrington. Other notable figures in the government were: John Profumo, Bill Deedes, David Ormsby-Gore and Robert Gascoyne-Cecil, 5th Marquess of Salisbury.
The Churchill ministry was mainly concerned with international affairs, the widening Cold War and decolonialisation (especially the Mau Mau Uprising and the Malayan Emergency).
Despite suffering a stroke in 1953, Churchill remained in office until April 1955, when he resigned at the age of eighty. He was succeeded by his ambitious protégé and deputy, Sir Anthony Eden, who finally reached the post he had coveted for so long; although his premiership was to last for less than two years.
Members of the Cabinet are in bold face.
