I'd be more inclined to think perhaps, maybe, possibly sufficient Brexiteer MPs might have had enough, and consider the deal a pragmatic way forward. NI issues with the EU aside, most of the nation will be out of the single market and customs union: and NI can be too if it decides it would rather the border was with the RoI than with the rest of the UK. It's not a good deal but it may persuade some who have no fear of revoke occurring, because surely there can't be sufficient MPs that daft, to go for it and see how things pan out. Saturday will be interesting.
