I thank the noble Lord for his observations. He goes some way towards explaining why we arrange for these agreements to be interpreted by lawyers, not diplomats. Of course entering into something such as the Northern Ireland protocol involves an element of political judgment; we have to accept that, and the Attorney-General was entirely candid about that. There is a political judgment to be made. There is in the agreement no express right of unilateral withdrawal, and we accept that as well. However, if one or other party decides not to obtemper their obligations, there are mechanisms to address that.
