Michael Heseltine, (born 1933) is a British businessman, Conservative politician and patron of the Tory Reform Group. He was a Member of Parliament from 1966 to 2001 and was a prominent figure in the governments of Margaret Thatcher and John Major. In 1990, he stood for leadership of the Conservative Party against Margaret Thatcher, and whilst he was unsuccessful, this triggered Thatcher's eventual resignation.A self-made millionaire, Heseltine entered parliament in 1966, entered the Cabinet in 1979 as Secretary of State for the Environment, and was Secretary of State for Defence from 1983 to 1986. In the latter role, he was instrumental in the political battle against the Campaign for Nuclear Disarmament. Heseltine was widely considered an adept media performer and charismatic Minister, although frequently at odds with Prime Minister Margaret Thatcher. He resigned from the Cabinet in 1986 over the Westland Affair and returned to the backbenches.Heseltine then returned to government as Secretary of State for the Environment, with particular responsibility for 'reviewing' the Community Charge, widely and correctly expected to lead to poll tax being abolished, allegedly declining an offer of the position of Home Secretary. After the 1992 general election he was appointed Secretary of State for Trade and Industry choosing to be known by the title, dormant since 1974, of President of the Board of Trade and promising to intervene "before breakfast, dinner and tea" to help British companies.Heseltine resigned his Henley-on-Thames constituency at the 2001 election, being succeeded by Spectator editor Boris Johnson, but remained outspoken on British politics. He was given a life peerage as Baron Heseltine, of Thenford in the County of Northamptonshire.
