Parliament will meet for a few days before it is prorogued.
The legislative route is theoretically still open, right? But they'd REALLY have to get their skates on.
A VoNC can still happen. A government of national unity can still happen theoretically, though it's going to involve some serious, grown-up compromises.
Part of me thinks this is a piece of theatre, to win populist support for a forthcoming GE with the aim of changing the parliamentary arithmetic. BoJo will look like the so-called "Champion of the People", Parliament as the "Evil Elite" to idiot Leavers. The polls at the moment are NOT favourable for the Remain cause - basically, everyone who is against a no deal exit will need to vote Labour to stop it, and that is going to require serious nose-holding on the part of centrists.
