I do not agree. My hon. Friend knows we have a difference of opinion, and I hope that he will move towards my position. I still hope that might be so, and I say that because one has to look at the mutual incentives and disincentives for both parties to stay in the arrangement. I made this point in December and, for the reasons I advanced in December and in my November opinion, the incentives or disincentives for the European Union are as profound, if not greater, to get us out of the backstop than to keep us in it. That is what I firmly believe. He may disagree, but that is what I believe.

That is why I have taken the political judgment that this withdrawal agreement needs to be supported but, in saying that, these improvements do make a difference. In the last line of my advice, I say there can be no lawful exit unless there is a fundamental change of circumstance. It is extremely important to remember that there is always a right to terminate a treaty unilaterally if circumstances fundamentally change. There is no question but that we have a right to exit if those circumstances apply.

- Hansard - - - Excerpts

Those of us who remember some infamously politicised legal opinions, as with the Iraq war, will want to acknowledge the Attorney General’s total integrity and independence, but can he explain to a non-lawyer how respect for the international rule of law is enhanced by a unilateral declaration to break it?

The right hon. Gentleman seeks to give with one hand and take with the other. With the greatest of diffidence and respect, he is not quite right. The unilateral declaration is not incompatible with international law. It reserves the United Kingdom’s right to take all measures available to it in circumstances where the talks have broken down as a result of a breach of article 5, which is the good faith duty. It reinforces and further stresses the United Kingdom’s right to take measures to withdraw from the arrangements if there is a breach of good faith.
