CAMERON TO NAME IS COLITION GV

British Prime Minister David Cameron started his first full day of work Wednesday, walking through the black lacquered door of his office at No. 10 Downing Street and into a raft of decision-making. High on the agenda will be appointing ministers to as many as 20 Cabinet positions. Liberal Democrat leader Nick Clegg, whose party entered a coalition with Cameron's Conservatives on Tuesday, was named deputy prime minister. In addition to Clegg's appointment, a Conservative Party source said Conservative Parliament member George Osborne has been named Chancellor of the Exchequer -- which is equivalent to treasury secretary -- and former Conservative Party leader William Hague has been appointed foreign secretary. Four other Cabinet posts will be filled by Liberal Democrats, Downing Street said. Formal announcements of Cabinet posts were expected later Wednesday, Downing Street said. The decision by Cameron and Clegg to enter a coalition capped five days of uncertainty that followed last Thursday's election, in which no party received a majority. Days of negotiations between the Conservatives, the Liberal Democrats, and the Labour Party of former Prime Minister Gordon Brown resulted in the announcement of a coalition between the Conservatives and Lib Dems. "I'm absolutely delighted that we do have a new government," Conservative spokesman Michael Gove told CNN on Wednesday. "I think the really important thing is that the policies that we were arguing for during the course of the election, and the policies of the Liberal Democrats, have now been brought together on a platform which will give the country exactly the type of government that it needs at this time -- strong and stable." Lib Dem leader Clegg said: "I hope this is the start of the new politics I have always believed in: diverse, plural; where politicians of different persuasions come together to overcome their differences in order to deliver good government for the sake of the whole country." Clegg sought to allay party members' concerns going into the arrangement. "I am acutely aware that I carry your hopes and aspirations with me into this coalition agreement," he said. "I can imagine this evening you will have many questions and maybe many doubts about this new governing arrangement. "But I want to assure you that I wouldn't have entered into this agreement unless I was genuinely convinced that it offers a unique opportunity to deliver the kind of changes that you and I believe in." Queen Elizabeth II named Cameron prime minister Tuesday night, shortly after Gordon Brown resigned, Buckingham Palace said. Brown had said Monday he would step down as leader of his party by the fall, but he changed course Tuesday, announcing he was quitting his party post immediately. His deputy, Harriet Harman, will lead the Labour Party until a leadership contest can be held, he told party activists. His party came in second, behind the Conservatives, in parliamentary elections last week, but no party won an absolute majority. Cameron, 43, becomes the country's first Conservative prime minister since the Labour Party, under Tony Blair, defeated John Major in 1997, and is the youngest for two centuries. Cameron echoed U.S. President John F. Kennedy's famous "ask not what your country can do for you" speech in his first remarks as prime minister. He aims to build a society "where we don't just ask, 'What are my entitlements?' but 'What are my responsibilities?'... Where we don't ask, 'What am I owed?' but more 'What can I give?'" Cameron said. "Those who can, should, and those who can't, we will always help," he promised, stressing freedom, fairness and responsibility. "Real change is not about what government can do," he insisted. "Real change is when everyone pulls together, comes together, works together." He also praised his Brown in brief remarks outside the prime minister's residence before disappearing into 10 Downing Street with his wife, Samantha. Coalition governments are extremely rare in British politics. The last time there was a "hung parliament" with no party holding a majority of the seats in the House of Commons was 1974. Coalition talks then between the Conservatives and Liberals failed, and a short-lived minority Labour government took power. But Cameron said Tuesday a coalition government was "the right way to provide this country with the strong, the stable, the good and decent government that I believe we need so badly." The two parties would command a clear majority in the 650-seat House of Commons, but have a number of key policy differences. Cameron said he wants "to put aside party differences and work together for the common good and the national interest." U.S. President Barack Obama was among world leaders who called Cameron shortly after the new prime minister entered Downing Street, according to a statement from the White House. During the call, Obama said he extended his congratulations and invited Cameron and his wife to visit the White House this summer. Cameron is Queen Elizabeth II's 12th prime minister -- including Harold Wilson twice, for his two non-consecutive terms -- since she was crowned in 1952.
