On the subject of private schools and not Diane Abbott's choice per se. I am unable to understand why, if you subscribe to the ethos of socialism, you think it's acceptable to opt for a private education for your offspring. A level playing field surely? anything else smacks of rank hypocrisy, particularly when you are in the habit of criticising colleagues choices, Harriet Harman, for sending her children to select state schools I believe. Select they may be, but they are still state.
There's an interview with David Lammy in The Sunday Times, he was one of 5 raised by a single mother, tougher I imagine than having a mother who is a Cambridge graduate and an MP where you can hardly claim to be anything other than upwardly mobile and as such, can insulate your children from the worst excesses of "the mean streets". David Lammy didn't have such a start, nevertheless he was the first black Briton to graduate Harvard Law School. Possibly he was helped along the way by winning a choral scholarship to a STATE boarding school.
