Before anyone sounds off about grammar schools, ask first where their children go to school

There’s a good reason and a bad reason why David Cameron hasn’t added his mite to the argument about the reintroduction of grammars, which his Education Secretary, Nicky Morgan, sounded off about yesterday. The good reason is that it would be the worst of form for the former Tory PM to diss his successor, even if he disagrees with her. The bad reason is that he’s got a dog in this fight; his son Elwen. You remember all the fuss about the rumour that little Elwen might be going to a feeder prep to St Paul’s, the private school? The Camerons invoked media privacy to see off discussion of that topic. Well, if true, and I haven’t checked since, it gives Mr Cameron a very particular take on the matter of academic selection. Because the whole point of the feeder preps is to prepare children to jump through the hoops that constitute the admissions exams for – to pluck an example out of thin air – Eton.
