Richard Edward Geoffrey Howe, Baron Howe of Aberavon,, known from 1970 to 1992 as Sir Geoffrey Howe, was a British politician who served as Deputy Prime Minister of the United Kingdom from 1989 to 1990. A member of the Conservative Party, he was Margaret Thatcher's longest-serving Cabinet minister, successively holding the posts of chancellor of the Exchequer, foreign secretary, and finally leader of the House of Commons, deputy prime minister and lord president of the Council. His resignation on 1 November 1990 is widely considered to have precipitated the leadership challenge that led to Thatcher's resignation three weeks later.
