David Miliband, he of the ‘sad eyes’ after ‘betrayal’, has departed the front bench. He remains in the Commons, but on inactive service and as what? Brooding presence, focus of retribution to the betraying brother? Unencumbered by duty, he can now expect devotion from the Conservative press and offers of lavish employment. Compare him with Denis Healey, who spent six years as defence secretary and five as chancellor before being passed over for Michael Foot – nice man, wrong choice – in 1980.
