David William Donald Cameron (born October 9, 1966) is the Prime Minister of the United Kingdom and Leader of the Conservative Party.
Cameron studied Philosophy, Politics and Economics at 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.
A first candidacy for Parliament at Stafford in 1997 ended in defeat but Cameron 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 coordination during the 2005 general election campaign.
With a public image of a young, moderate candidate who would appeal to young voters, he won the Conservative leadership election in 2005. His early leadership saw the Conservative Party establish an opinion poll lead over Tony Blair's Labour; the first in over ten years. Although they fell behind shortly thereafter when Gordon Brown became Prime Minister, under Cameron's leadership the Conservatives have been consistently ahead of Labour in the polls.
In the 2010 general election held on May 6, the Conservatives gained a plurality of seats in a hung parliament. Brown resigned and Cameron was appointed Prime Minister on May 11, 2010, on the basis of a coalition between the Conservatives and the Liberal Democrats. At the age of 43, Cameron became the youngest British Prime Minister in 198 years. The Cameron Ministry is the first coalition government in the United Kingdom since the Second World War.
