Utter the word ‘retirement’ in 4 Millbank at your peril. The bods at Sky News are waiting for the arrival of their new political editor, Faisal Islam, who is working out his notice period at Channel 4. Mr S hears that Adam Boulton, the outgoing political editor, is snapping at anyone in the office who says that he is retiring. Staff members are curtly reminded to say that Boulton is being ‘promoted to Editor-at-Large’, and he’s certainly not planning to go anywhere yet. ‘It’s the easiest way to wind him up,’ chortles my camera-wielding mole.
