Sir John Major, KG, CH, PC (born 29 March 1943) is a British politician who was the Prime Minister of the United Kingdom and the Leader of the Conservative Party from 1990 to 1997. He served as Foreign Secretary and then Chancellor of the Exchequer in the Thatcher Government from 1989 to 1990, and was the Member of Parliament for Huntingdon from 1979 to 2001.

Within weeks of becoming Prime Minister, Major presided over British participation in the Gulf War in March 1991 and negotiated the Maastricht Treaty in December 1991. He went on to lead the Conservatives to a fourth consecutive election victory, winning the most votes in British electoral history with over 14 million in the 1992 general election, with a reduced majority in the House of Commons. After defeat, Major resigned as Prime Minister and was succeeded as Leader of the Conservative Party by William Hague. Major is currently the oldest living former UK Prime Minister and remains an active speaker and businessman.
