My right hon. and learned Friend is to be commended for his statement, and also for the document that has been produced, which I have to say from my own experience is rather fuller than any advice he might ever have been called upon to produce. It might be helpful to the House if he could take this opportunity to confirm that there is nothing in this document that is incompatible with any advice that he gave to the Government? I would not expect him to be in a position to endorse any such document if it were at variance in that way. Secondly, turning away from that first principle to the content, might he also wish to comment on the provisions specific to Northern Ireland in paragraphs 25 to 29, which appear to show quite clearly that under the protocol it would be possible to end up with a situation in which there were in fact checks and controls on good passing between Northern Ireland and the rest of Great Britain?
