For the Conservative Party, hoping to rediscover the way back to Downing Street, reform of Britain's state-funded education system is an open goal. The ball is inside the six-yard box; all David Cameron needs to do is smash it in the net. He will not have a better opportunity to win over traditional Labour voters than by showing them how he can help their children escape from schools for losers. If he lacks the will to admit that grammar schools did more for working-class children than a thousand free school meals, he should at least promise to reintroduce with unambiguous rigour the standards, discipline and ambition that grammars delivered for people like me.
