David Cameron taunted the Labour front bench and called for a reaction after he was quizzed by backbenchers on welfare reforms.
He was asked by Labour Katy Clark about benefits for disabled children before Conservative David Nuttall asked for an end to the "something for nothing culture".
The prime minister asked the senior Labour MPs to nod in agreement with his planned changes before accusing them of a "great big vacuum".
