Ed Miliband asked David Cameron what he planned to do to stop it from happening. David Cameron was not clear in his response other than trying to win cheap political points.
Ed also asked him about housing and the fact that too many land owners are sitting on their land with little intention to build.
David Cameron's response was similar to the bankers response, where threw some insults at Ed without answering the question.
It was a tough PMQ for Ed who wants to focus on policy and not sound bites. But unfortunately for him David Cameron is very much likes sound bites.
Ed will probably need to go back to the drawing board or each week the political pundits will say that it is a win for David Cameron and Ed does not need to give David any kind of advantage.
