Of course Parliament is allowed to change its mind. It does so on many occasions and no doubt will do so in future on other issues.
It is our view that the question of whether to leave and the process of approving how we leave have been decided. Parliament approved the referendum and has signalled its approval to every step the Government have taken since July 2016. Furthermore the people authorised the Government’s negotiating position as a result of the election last year. Lastly, we have made a solemn promise to seek approval, which I am confident will be granted, from Parliament of the outcome of those negotiations.
I stress that I understand many noble Lords’ deeply and honestly held conviction that the UK should not leave the EU. That has become very clear to me throughout the progress of the Bill, but this is a Bill to provide maximum legal certainty upon exit. I do not think it would be in the interests of either the EU or the UK to open the door to an ever-continuing negotiation process with no certainty that the UK will ever reach a new settled relationship with the EU. I do not believe that that is what the noble Lord intends, but that is what is being risked. The terms of the vote on the final deal are clear: to accept the terms of the agreement or to move forward without a deal. This is fully in line with the terms on which the European Parliament will be voting: a yes or no vote.
Amendments 196 and 213 are unnecessary because we have already made a strong commitment to hold this vote as soon as possible after the negotiations have concluded.
