Northern Ireland Protocol Bill

My right hon. and learned Friend speaks wisely about these topics, as ever. He refers to the doctrine of necessity and the tests that must be met. I think he will agree that, whether it be imminent or emerging, there has to be evidence that the high threshold is met. Does he think that, in common with the approach adopted in the United Kingdom Internal Market Bill, if there is evidence so pressing as to justify a departure from an international agreement, with the risks that that involves, it should be brought back to this place for the House to decide in a vote? As was then suggested in that Bill, on the evidence available, there should be a parliamentary lock on the use of that important step.
