50 People Who Matter 2010 | 15. David Cameron
Britain's youngest Prime Minister since 1812, David Cameron led the Conservatives back into government after 13 years in opposition.
In his first months, he has set out a bold policy agenda, including a vastly reduced role for the state. The long-term success of his government is likely to depend on how the public reacts to the coming cuts, which he has said will "change our way of life" for decades to come.
