Red Ed's at war.

They may be 12 points ahead in the polls but they certainly aren't behaving like a government in waiting.

Instead, relations between Red Ed Miliband and Red Ed Balls have got even worse.

Daily Mail today reports that the relationship between the Red Eds' is now as bad as it was between Tony Blair and Gordon Brown.

The Miliband camp have recently been briefing about Balls' 'alpha male posturing', policy differences between the two, domineering, secrecy and there's even a rumour that Miliband had a blazing phone row with Balls.

How credible is that?
