on the issue of more defecting Tories, if it turns out that they have also been in talks for months then I can understand it. But if they have just made a snap decision to switch then I agree with the sentiment that it's too little, too late.
They can sit with the opposition if they wish, but Labour shouldn't be offering them the chance of re-election. They need to prove themselves.
I'm really interested to see if this VoNC goes forward.
