Kenneth Clarke, English politician, Lord High Chancellor of Great Britain
Kenneth Harry Clarke, Baron Clarke of Nottingham, (born 2 July 1940), often known as Ken Clarke, is a British politician who served as Home Secretary from 1992 to 1993 and Chancellor of the Exchequer from 1993 to 1997 as well as serving as deputy chair of British American Tobacco from 1998 to 2007. A member of the Conservative Party, he was Member of Parliament (MP) for Rushcliffe from 1970 to 2019 and was Father of the House of Commons between 2017 and 2019. The President of the Tory Reform Group since 1997, he is a one-nation conservative who identifies with economically and socially liberal views.

Clarke served in the Cabinets of Margaret Thatcher and John Major as Chancellor of the Duchy of Lancaster from 1987 to 1988, Health Secretary from 1988 to 1990, and Education Secretary from 1990 to 1993. He held two of the Great Offices of State as Home Secretary and Chancellor of the Exchequer. He contested the Conservative Party leadership three times—in 1997, 2001 and 2005—being defeated each time. Opinion polls indicated he was more popular with the general public than with his party, whose generally Eurosceptic stance did not chime with his pro-European views. He returned to Cabinet under David Cameron as Justice Secretary from 2010 to 2012. He was Minister without Portfolio from 2012 to 2015 and the United Kingdom Anti-Corruption Champion from 2010 to 2014.

The Conservative whip was withdrawn from him in September 2019 because he and 20 other MPs voted with the Opposition on a motion; for the remainder of his time in Parliament he sat as an independent, though still on the government benches. He stood down as an MP at the 2019 general election and was thereafter appointed by Boris Johnson as a Conservative Member of the House of Lords in September 2020.

Clarke is President of the Conservative Europe Group, Co-President of the pro-EU body British Influence and Vice-President of the European Movement UK. Described by the press as a 'Big Beast' of British politics, his total time as a minister is the fifth-longest in the modern era. He has spent over 20 years serving under Prime Ministers Edward Heath, Margaret Thatcher, John Major and David Cameron. He was one of only five ministers (Tony Newton, Malcolm Rifkind, Patrick Mayhew and Lynda Chalker are the others) to serve throughout the whole 18 years of the Thatcher—Major Governments, which represents the longest uninterrupted ministerial service in Britain since Lord Palmerston in the early 19th century.
