That Corbyn fella...

This has been discussed in the Brexit thread, but this is surely the start of the revocation process?

Is it possible they're having to get on with because May's position is now so tenuous?

Well, he doesn't quite say that. He says he voted 'remain' and hasn't changed his mind, but as a second referendum is purely hypothetical, he doesn't actually say he would vote 'remain' in it. I don't think it's a 'game changer', he's just being honest and answering the question fairly casually, as it's not a big deal (and all those who pretend it is are probably just looking for the big political story of the day; that said, by the way she gave her answer, May certainly made it into a bigger issue for herself--it's a bit like the 'what's the naughtiest thing you've done?' question, which Corbyn adroitly deflected and May made a complete mess of). At the same time, he stresses that Labour respects the referendum result.
