David Cameron response was weak and even his own party did not really seem to be supporting him. I think it is bit ridiculous of David Cameron to blame Labour for NHS Wales when he is Prime Minister of the whole country.
So I think that Ed Miliband won the exchange by sticking the facts and highlighting that David Cameron is responsible for NHS England which is having some serious problems.
These are the kind of exchanges that are important for Ed Miliband to win he has any realistic chance of becoming Prime. Minister in eight months time.
