Oh dear, Ed

Ed Balls is a man with ambition. So expect him to really, really, really regret shouting "so what?" when David Cameron claimed that the UK tax burden is "the highest in history" his response to Alistair Darling's budget. The fact that Ed's face went deep purple when Cameron called him on it suggests that he knows that little throwaway remark will come back to haunt him.

It's about taxes, Ed. Government is always about taxes.
