Too bad there isn't any provision under which the Labour MPs get a chance to vote whether they want to keep him as their leader or not. Of course there's nothing to stop him inviting them to do that, the same way John Major did at one point, but I very much doubt if he will - the chances are they'd tell him to step down.

If he couldn't get a majority over this, he hasn't a chance of getting a majority on a lot of other isssues. I rather suspect that as that realisation sinks in, we may be told that his health has taken a turn for the worse, necessitating a resignatiion on health grounds, that being the traditional way in such situations.
