Northern Ireland Protocol Bill

My right hon. Friend makes a very important point. Does he agree that, from a legal perspective, if article 16 were to be triggered, at least we would be able to argue that we had used all means available to us under the protocol, as is necessary to meet the necessity test—in other words, that the state has exhausted all the options open to it before it acts unilaterally? That is exactly the value of using article 16.
