When he’s not running a football club or advising Bank of America, part-time MP David Miliband teaches politics to the students of Haverstock School in Chalk Farm. He apparently “taught the theory/practice of ministerial accountability this morning.” No doubt without a trace of irony.

As a minister Miliband was hardly the most loyal of servants to his Primus Inter Pares. Triggering various leadership crises and letting his disdain be well-known. Presumably that’s the practice part of the lesson.

Miliband’s less than exemplary record in government has even come under attack from William Hague. Finding his recently lacking quick wit, Hague quips about being Foreign Secretary to this month’s Total Politics; “this isn’t a launch pad to one day be leader again, which, I think must be a great distraction, and has been for some of my predecessors.” Miaow.
