Labour MP attacks Balls.

Labour MP John Mann has this evening launched a scathing attack on Shadow Chancellor Ed Balls.

In a statement Mr Mann said that - "Ed Balls failed to defeat Osborne when Osborne was by far the most vulnerable Cabinet member."

"There was a time when it was felt Ed Miliband was running to catch up with Ed Balls." "That's reversed in the past year."

"What happened last week crystalises that change."
