Balls versus Gove is a battle the former won’t let go. He has managed to force an apology out of Gove for the glaring cock-up of publishing two different lists of which schools would not be getting money promised to them in Labour’s scorched earth-bonanza. A humiliating position for the Secretary of State and for all his faults Balls is the only leadership contender to be scoring hits on the coalition.

For all Ed Miliband’s poetry, it is Balls who is showing Unite which Ed it is that can stop not only David but Dave too.
