I will not give way, as I am going to make some progress.
The choice on the final deal is clear: the British Parliament can veto the exit agreement and/or the terms of the new relationship agreement, but in that case Britain would leave the EU without agreeing terms. On the new relationship agreement, the UK Government would of course be free to revert for further negotiations, but that could not delay or stop Brexit from happening under the terms of article 50. Those facts will rightly and understandably focus our minds, as they are doing here today, and with a sense of trepidation. They will also focus minds—this is why it was crafted in the way it was—on the other side of the channel, among our European friends. So, on the assumption that it would take at least 18 months to agree all the terms of any new relationship agreement, the idea that Parliament voting down any deal would send the UK back to a further round of meaningful negotiations, before Britain formally leaves, is at odds with the procedure in the Lisbon treaty, and I find it neither feasible nor credible.
