As Jeremy Corbyn fights to cling on as Labour leader, and most of his MPs hope Owen Smith will replace him, please spare a thought for the one man caught up in the middle of this turbulence: Andy Burnham, still very much the shadow home secretary.

Yes, that's right. Andy Burnham, who was in Tony Blair's Cabinet. Andy Burnham, the Blairite. That Andy Burnham. The one who then served in Gordon Brown's Cabinet. The Brownite. Andy Burnham. The one who thought Jeremy Corbyn would be a "disaster for the Labour party", and then went on to serve in his shadow cabinet.

What in the name of all that is holy is he still doing there?

We know Mr Burnham finds Labour infighting terribly upsetting. He didn't follow his friend James Purnell out of Gordon Brown's cabinet in 2009. He stood back and let Ed Miliband lead the party to failure because, as he later admitted, he was too much of a "team player". True to form, he won't join the anti-Corbyn plotters as he wants "members to decide who leads our party".
