The PM was wise to keep Mr Darling and his accountant tied to the mast, and to keep Mr Miliband close by. It was sensible to promote the potentially dangerous Alan Johnson. Mr Mandelson seems to be calling the shots, and has the Hesletine slot as Deputy PM as reward.
He may now be able to cling on. It all depends on how many junior Ministers now resign in anger, and how many Labour MPs demand change. My guess is the ship remains becalmed and holed but stays afloat a little longer.
