I cannot prove what motivates the Prime Minister, but he smells like one of those tiresome people who feel the need to apologise for their own accidents of birth. Mr Cameron had the good fortune to be born to respectable, well-heeled parents who paid for him to go to Eton. With the help of that school’s superb teaching, he went to Oxford. He has never really had to work for a living. He has gone into the public service, which most people would consider a “fair” return for his privileges. Yet his guilt trip continues. He has calumniated his old university. I wonder whether he will take the precaution of having someone tot up for him how many boys from south London council estates are at Eton, before he looses off his tongue at that part of his past too?
