Laura Kuenssberg tweets that No10 is nevertheless sticking to its line:
"No 10 source - Cameron shd have said black Caribbean but says the figures are 'still terrible' + says , 'what world is Oxford living in?"
So what world — as No10 puts it — is Oxford living in? That's a very good question. I'd say it's a world where international competition between universities has never been more fierce. Its admissions policy should be unashamedly meritocratic. It is the job of schools, not universities, to teach kids properly and promote social mobility through excellence for all. When universities are used as a branch of the welfare state, they go to ruin.
Oxford is also living in a world where black children in Britain are given a pretty poor education. You can argue that black kids are more likely to come from poor households, and that sink schools cheat poor kids regardless of their racial background. But if the Prime Minister is looking for someone to blame, he should look first at the secondary school system — which, to his immense credit, is being rapidly reformed.
If Oxford was rejecting a proportionately higher number of black students than it was white students, there might be a case to answer. But as far as this Glasgow graduate can make out, Oxford's admissions hold a mirror up to the British schools system. One where the rich are educated best, and the poor are shafted. This, alas, is the world that Oxford is living on.
In last week's Spectator, Ivor Roberts looked at an argument that is increasingly being heard in Oxford: that it should just go independent and finally sever ties with the politicians. The more Oxford is blamed for the failings of the state education system, the more tempting this option must be.
UPDATE: Matt d'Ancona writes that Cameron's statement itself is fine: ie "I think that is disgraceful, we have got to do better than that". I agree. Perhaps that's what Cameron meant. But it was the No10 briefing later - tweeted by Laura - which made this sound so much worse.
