I bow to the noble Lord, who has immeasurably more knowledge and experience of Northern Ireland than I could possibly have, but of
course I have read the Northern Ireland agreement and understand that there are two documents in international law. The simple point is that, in the protocol, we agreed the means by which we take the view that the Good Friday agreement should be implemented in the context of the United Kingdom leaving the EU. That is what we agreed; we cannot now say that we are going to resile from it unilaterally. It is as simple as that.
