PMQs: Cameron and Miliband on Major and power bills

Ed Miliband quoted a reply from the prime minister at last week's PMQs about Labour's plan for an energy price freeze which David Cameron said was the policy of someone living in a "Marxist universe".
But the Labour leader said the "red peril has claimed Sir John Major" after the former prime minister spoke out about energy bills on Tuesday.
The pair clashed on energy policies, green levies, and what to do about bills during PMQs, where David Cameron called Sir John a "good man", but claimed the Labour leader was acting like a "conman".
