So in a sense, it’s not news to see him suggesting that Downing Street and the PM have “botched” the plan to make all English schools into academies.

But it is news, of course, because of what it says about the state of relations between senior Conservatives in the context of the referendum.

Simply, the rage and vitriol of the campaign is boiling over, drawing Tories into new fights that have little or even nothing to do with the European Union.

Mr Cummings, keen to make the case that David Cameron and his team are incompetents who can’t be trusted to get Britain a good deal in Europe, has now handed ammunition to Labour MPs, teachers’ leaders and Tory council chiefs who don’t like the academies plan.

They will now cheerily fire Mr Cummings’ bullets straight at Nicky Morgan, the education secretary currently taking fire for a policy the announcement of which probably has more to do with George Osborne and Mr Cameron than her.

And people who fret about their kids’ education will quite likely conclude that the Conservatives are doing something that might hurt that education. After all, the man who used to help run Conservative education policy says the policy is “cackhanded” and the people behind it don’t care about children, just headlines.
