This deal was never going to be voted through no matter who put it forward. It leaves us in an ever worse position then we currently are. Possibly being leagly tied to the EU indefinitely with no getout for us but with no say in the EU, it was a very bad deal. I would have very upset if they had voted it through. But then are the EU ever going to give us a reasonable deal to leave I think not, but even they keep saying they don't want a no deal.
The government needs to stop arguing amongst themselves and get on with it though.
Coming from a vote remain. I'm not sure there is any going back now.
