SIR KEIR STARMER bid farewell to the Commons front bench today with spiteful smears against his predecessor as his successor deliberated how far he is willing to move beyond the failures of Starmerism.Parliamentary speculation about incoming premier Andy Burnham’s Cabinet picks reached fever pitch while Sir Keir declared his “political journey at an end.”Mr Burnham is set to be elected Labour leader on Friday and will take over in Downing Street on Monday, despite a quixotic move by Bermondsey MP Neil Coyle to nominate a rival.
