It is rare to see genuine emotion slash through the protocol and buffonery of PMQs but today Cameron almost lost his rag, and rightly so.

Brown has been riding the wave of popularity surrounding his handling of the financial crisis for the past few weeks. Today was a stark reminder of his utter inability to handle any issues that stray into the messy arena of of the human and how Labour has failed those it has pledged to protect.

What this problem will mean for the Labour party, which Emily Thornberry smugly described as “back in the game” yesterday, only time will tell. But to me, this is evidence enough that the failings of this administration cannot be measured on the balance sheets.
