Michael Heseltine (born 1933) is a Conservative politician. In 1990, his leadership challenge sparked the process that ended Margaret Thatcher's time in power. By 1995 he was Deputy Prime Minister and First Secretary of State under John Major.
In 1989 two of Britain's smaller parties, the Social Democrat Party and the Liberal Party, merged to become the Liberal Democrats (Lib Dems). By the early nineties this new party, under its leader Paddy Ashdown, had become more of a threat to the two main parties. But this threat only translated into any sort of power for the Lib Dems after the 2010 election brought an uncomfortable coalition of Lib Dems and Conservatives to power.
