Northern Ireland Protocol Bill

The right hon. Gentleman knows with what affection I regard him, his party and Northern Ireland, having had the privilege of being Advocate General for Northern Ireland. What he is saying is a very good case for triggering article 16, which was the entire purpose of the inclusion of article 16 in the protocol. It is not necessarily a good reason, however, for changing the entire basis of the treaty, including writing out the jurisdiction of the Court of Justice of the European Union, and so on. How do we get from a position where we have societal impacts, with which I am perfectly willing to agree, to a position where we virtually rewrite the terms of a treaty that we solemnly signed only two and a half years ago?
