Ryan: David Cameron take his place as the PM of the UK

Conservative leader David Cameron has become the new UK prime minister after the resignation of Gordon Brown.

Mr Cameron, 43, entered 10 Downing Street after travelling to Buckingham Palace to formally accept the Queen's request to form the next government.

He said he aimed to form a "proper and full coalition" with the Lib Dems to provide "strong, stable government".

His party won the most seats in the general election last week, but not an overall majority.

In a speech outside his new Downing Street home, Mr Cameron said he and Lib Dem leader Nick Clegg would "put aside party differences and work hard for the common good and the national interest".
