Of course which is why noone should have paid much mind when they said they wouldn't vote the customs amendment. If push comes to shove their going to kill this deal one way or another because having it just pass isn't really an option for them.
Not even that, the cu amendment is a thinly disguised, let's fuck shit up, amendment that exists to scupper the government and destabilise it wholesale.
I doubt more then a few dim souls, in the con side, fully expect a cu to be actually added by the gov at the end of tomorrow or at all. They will vote for it in a, very likely, majority tomorrow on the basis it rips the tories apart and clears a path to a GE. Same for the second ref, and to block off no deal amendment.
The dup are proper pissed off and are looking for Tory blue blood. So is everyone else.
Edit: Wow just read some of the WA tweets, no wonder the gov tried to do what they did on sat. This is going to send shockwaves to those who tried to support it on Saturday, including labour rebels.
The whips now have a whole bunch of new talking points to use with the rebels.
