Brexit is going to ultimately get cancelled if May loses tonight, isn’t it?

[Burney]

She'll hold a third vote, which will obviously pass, you dozy b*astards

Right now, Labour MPs are going mental because she’s going for the blackmail option.
If you think they’re going to abstain, you’re a mong.
Labour ultimately wants to be able to say ‘Tory Brexit, blah, blah’ afterwards. Abstention doesn’t give them that. They’ll be whipped to vote against.
So it comes down to the DUP and the ERG.
Still think No Deal can’t happen?

I've never said Labour would abstain en masse, or indeed at all.

In your scenario, the numbers could be pretty tight, but I think the DUP would fall into line as when it comes to the crunch they don't have any hard Brexiteer ideologues in their ranks and would rather May's deal than No Deal. That would then bring over enough ERG members for her deal to pass.
