So Ken called Kate Hoey a "semi-detached member of Labour". Hmmm. That was him a few years ago. At that point he seemed to make a virtue out of it. Rattled is the word which comes to mind.
Hoey's action really presents Labour with a dilemma. With Gordon Brown having made a virtue of GOATS (Government Of All The Talents) they can hardly complain when Boris seeks to be inclusive too. But Labour MPs will be hopping mad and seeking retribution. There will be demands for the whip to be withdrawn on the pretext of her semi-endorsement of a non Labour candidate. You can bet your bottom dollar that they won't do it until after Thursday, though.
