I actually feel a bit foe Sir Kier.
He is stuck between a rock and a hard place, the man is certainly intelligent enough to know what is wrong but he cant do anything about it. Perfect example was trying to get rid of the gob on a stick - he is immediately pushed into giving it another 'prime' role. Just how anyone would think that she could do well against Gove (and I dislike him too!) is beyond me.
If I was Burnham I would sit it out a while, labour are nbot going to sort themselves out any time soon, no leader could bring them together at the moment far too many parties within the party.
