Election 2010: David Cameron becomes new UK Prime Minister

David Cameron has moved into number 10 Downing Street after becoming the UK's new Prime Minister.

There was no overall winner after the general election so the government will be made up of Tories and Lib Dems.

The UK has its first Conservative leader for 13 years and the first coalition government in 70 years.

David Cameron says he's ready to serve Britain.

He said: "I came into politics because I love this country and I think its best days still lie ahead and I care deeply about public service.

"Our country has a hung parliament where no party has an overall majority and we have some deep and pressing problems; a huge deficit, deep social problems and a political system in need of reform."

He became the youngest Prime Minister since 1812 after Gordon Brown went to see the Queen and resigned as Prime Minister.

In his leaving speech he paid tribute to his staff and family.

He said: "I thank my sons John and Fraser for the love and joy they bring to our lives and as I leave the second most important job I could ever hold, I cherish even more the first - as a husband and father."

Gordon Brown also paid tribute to members of the Armed Forces.

Harriet Harman will stand in as leader until the Labour party chooses a new one.

Change

The Lib Dems approved the deal late last night (11 May). There will be five from the party in the cabinet out of a total of 22 jobs including Nick Clegg, who's been made deputy Prime Minister.

He says working together won't always be easy.

He said: "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.

"Diverse, plural, where politicians of different persuasions come together, overcome their differences in order to deliver the good government for the sake of the whole country.

"There will of course be problems, there will of course be glitches. But I will always do my best to prove that new politics isn't just possible, it is also better."

William Hague is the new foreign secretary, George Osbourne is chancellor and his number two will be the Lib Dem Vince Cable. He will deal with the banks.

Other big jobs which could go to them include education and the home office.

The changeover was ruthlessly quick with Gordon Brown leaving, going to see the Queen, then within 90 minutes David Cameron was in Downing Street.

The new government is very different.

The Tories and Lib Dems picked each other apart during the campaign. Now they are on the same team and hope it will last for years.

Each side had to ditch some things to get the deal done and it's an extensive agreement.

The Lib Dems get plans to change tax, so anyone on less than £10,000 a year won't pay it.

They also get the promise of a referendum, a national vote, on changing how we choose our MPs.

The Conservative plans to start cutting and paying back the vast deficit we owe will start now, as they always insisted.
