David Cameron is the prime minister of the UK and the leader of the UK's Conservative Party.
David Cameron became the prime minster of the United Kingdom in May 2010, leading a coalition government (the UK's first since World War II). He was elected leader of the Conservative Party in December 2005, and has been a Member of Parliament for the Witney constituency since 2001. Before he became an MP, he was a Special Adviser to the Chancellor of the Exchequer and then to the Home Secretary. He took a break to work in media for seven years, then stood for election in 2001 on an agenda of tax-cutting. (During the election, he also wrote a column for the Guardian.) As a new MP, he took several controversial positions, such as coming out in favor of the "harm reduction" drug policy. He became a member of the shadow cabinet (an alternative cabinet to the party in power) in 2003, and two years later became head of the party.
