Liberal Democrat leader Nick Clegg has said he has had disagreements with Prime Minister David Cameron and said the pair are "open" about this.

He said: "Anyone who knows my views on everything from Iraq to civil liberties, from political reform to reform of the tax system, knows that what I represent as leader of the Liberal Democrats is a long, proud tradition of radical, progressive liberalism.

"And it's different to the kind of heavy-handed statist sort of approach of government-knows-best from Labour and it's different from the kind of conservatism that the Conservative party's represented down the ages. And I'm very proud of the fact that we're now able to implement those values in government."

Mr Clegg said he thought it was a "refreshing change" for those at the peak of power to admit they "don't agree on everything".
