Andy Burnham appeared to be in full retreat today as he said Sir Keir Starmer was the right person to be Prime Minister. The Greater Manchester mayor offered his backing to Sir Keir despite having previously fuelled speculation he was poised to mount a Labour leadership challenge. But - despite leaving the door open for a future leadership bid - Mr Burnham seemed to be backing away on Monday following a backlash against his posturing. 'There's no ability for me to launch,' Mr Burnham said, as he sought to address claims he was being 'disloyal' and 'completely out for myself'. But he cast doubt on whether Sir Keir would be the leader to achieve such a turnaround.
