, LONDON, May 12 – David Cameron finally took office as British premier on Tuesday, ending his Conservative party\’s 13 years in opposition and vowing to form a "strong and stable" coalition after inconclusive elections.
The 43-year-old — who becomes Britain\’s youngest prime minister for some two centuries, with a pregnant wife — was appointed after Gordon Brown admitted defeat following five days of political limbo.
President Barack Obama called Cameron within minutes of his appointment by Queen Elizabeth II, inviting him to visit the United States in July.
It was the first in a flurry of congratulatory phone calls from world leaders, including German Chancellor Angela Merkel, French President Nicolas Sarkozy and Australian Prime Minister Kevin Rudd.
Speaking outside 10 Downing Street, the young Tory said he would form a "full" coalition government with the Liberal Democrats, who emerged as kingmakers from last week\’s cliff-hanger general election.
"I aim to form a proper and full coalition between the Conservatives and the Liberal Democrats," he said, flanked by his wife Samantha in a simple blue dress revealing her five-month pregnancy bump.
"I believe that is the right way to provide this country with the strong, the stable, the good and decent government that I think we need so badly."
Lib Dem head Nick Clegg was named deputy premier, with his party agreeing early Wednesday to back the deal and form Britain\’s first coalition government since World War II.
"We are going to form a new kind of government," Clegg told his lawmakers, adding he hoped it marked "the start of the new politics I have always believed in."
Other appointments included 38-year-old George Osborne as chancellor — facing daunting economic challenges including a eurozone crisis — and William Hague as foreign minister.
The dramatic confirmation of Britain\’s new leader came after days of uncertainty in the wake of Thursday\’s election, which produced no clear winner for the first time since 1974.
Brown had announced he was quitting just an hour and a half before Cameron walked through the front door of 10 Downing Street.
He wished Cameron well as he departed from top-level politics, while acknowledging the personal weaknesses — such as poor presentational skills and impatience — which hampered his three-year premiership.
"Only those who have held the office of prime minister can understand the full weight of its responsibilities and its great capacity for good," Brown said.
Brown then walked down the famous street for the last time holding hands with his wife Sarah and their two young sons John and Fraser, who were making a rare public appearance.
Brown had said he would resign as Labour leader Monday but could have stayed on for several months as a caretaker had Labour struck a deal with the Lib Dems.
He has spoken to his predecessor Tony Blair by phone. Labour deputy leader Harriet Harman will act as caretaker leader while a leadership campaign takes place, which is expected to conclude by September.
Some 40 minutes after Brown, Cameron arrived at the palace with his wife for a ceremony with the queen known as the kissing of hands. A statement from Buckingham Palace confirmed he had been asked to form a government.
In the election, the Conservatives won 306 seats in the 650-member House of Commons — 20 short of a clear majority of 326 — followed by Labour on 258 and the Lib Dems on 57.
After five days of talks between the Lib Dems and Tories — and briefly between the Lib Dems and Labour — the two parties finally struck a deal.
Clegg — who is leading a Liberal party into British government for the first time since David Lloyd George left power in 1922 — was among five Lib Dem cabinet ministers in the new government, Downing Street said.
Critics say the deal between the centre-right Conservatives and centrist Lib Dems is an unlikely alliance, since they have strongly differing views on a number of issues.
But between them, they have enough to secure a majority in the House of Commons which Labour and the Lib Dems, seen as more natural bedfellows, did not.
There were already doubts about the political union Wednesday, however, with the Conservative-supporting Telegraph newspaper warning it would be "unsatisfactory and short-lived."
"Even as they applauded the statesmanship of their leaders, there were voices in both parties predicting the marriage would not last," added the Financial Times.
