My hon. Friend is absolutely right, and on top of that powerful point the effect of this deal is to give up control, and it would precipitate a democratic cliff edge. That is compounded by the lack of an exit mechanism we can control. It gives the EU a veto over any UK exit from the backstop, even if negotiations on the future relationship languish for years or break down entirely. It is clear that none of the subsequent assurances alter the legal position as set out in the withdrawal agreement.
