Labour MPs Stella Creasy's question to the Prime Minister about private financing of public services didn't go down well with Conservative MPs.
The backbencher asked the question about the amount of money her local hospital had to pay in PFI fees during PMQs.
She was met with a wall of sound from Tories presumably pointing out that the policy was championed by the last Labour Government.
The Walthamstow MP and former Labour deputy leader candidate didn't let the shouting stop her from asking her question, however.
After Ms Creasy had finished her question David Cameron responded that the Government was trying to unpick the problems which he said were caused by the last Labour government.
