David William Donald Cameron ( born 9 October 1966) is the Prime Minister of the United Kingdom, First Lord of the Treasury, Minister for the Civil Service and Leader of the Conservative Party. He represents Witney as its Member of Parliament (MP).
Cameron studied Philosophy, Politics and Economics (PPE) at Brasenose College, Oxford, gaining a first class honours degree. He then joined the Conservative Research Department and became Special Adviser to Norman Lamont, and then to Michael Howard. He was Director of Corporate Affairs at Carlton Communications for seven years.
He was defeated in his first candidacy for Parliament at Stafford in 1997, but was elected in 2001 as the Member of Parliament for the Oxfordshire constituency of Witney. He was promoted to the Opposition front bench two years later, and rose rapidly to become head of policy co-ordination during the 2005 general election campaign. With a public image of a youthful, moderate candidate who would appeal to young voters, he won the Conservative leadership election in 2005.
In the 2010 general election held on 6 May, the Conservatives won 306 seats in a hung parliament. After five days of negotiation, Cameron formed a coalition with the Liberal Democrats (Lib Dems). Cameron leads the first coalition government of the United Kingdom since the Second World War. The 43-year-old Cameron became the youngest British Prime Minister since the Earl of Liverpool 198 years earlier.
