David Cameron and Ed Miliband clash over funding

David Cameron and Ed Miliband clashed over party funding and Labour's links to the unions at a stormy Prime Minister's Questions.

Struggling to be heard above the roars of MPs on both sides, Mr Cameron told the Labour leader the unions "own you, lock stock and block vote".

Mr Miliband hit back by saying the PM was "owned by a few millionaires at the top of society".

His call for a cap on political donations was rejected by the PM.
