Mr Balls claimed that the Miliband camps had been briefing against each other. He told Total Politics Magazine that Ed's supporters had been attacking David's "personality", while David's backers had criticised his brother's "decision making".
quote from Balls:
Between the brothers there has been a little bit of off-the-record briefing going on. Hopefully, the two of them will say to their supporters to stop it. It is pretty unedifying.
