Britain's David Cameron becomes PM

[May 11 2010]

David Cameron, the youthful leader who modernized the party of right-wing icon Margaret Thatcher, became prime minister Tuesday after the resignation of Gordon Brown — capping a gripping election saga that returns the Tories to government after 13 years of Labour Party rule.

Following tradition, Queen Elizabeth II appointed Cameron at Buckingham Palace — a stately denouement to a behind-the-scenes dogfight between Cameron and Brown for the cooperation of Britain's third-place party, after an election that left no party with a majority.

Within minutes, the 43-year-old Cameron was installed at No. 10 Downing Street, becoming the youngest prime minister in almost 200 years, since Lord Liverpool took office at age 42.
