Joke comes back to haunt Cameron

David Cameron was left red faced after being forced to admit he once branded his new coalition partner Nick Clegg a "joke".

In a light-hearted moment, Mr Clegg pretended to storm off – prompting Mr Cameron to plead with him to "come back".

The incident referred to a 2008 book in which Mr Cameron was asked for his favourite joke and responded: "Nick Clegg, at the moment."

Asked about the jibe and whether he now regretted it, Mr Cameron turned to Mr Clegg and confessed: "I'm afraid I did".
