It is a statement of the legal position to say that to enter into a permanent arrangement, we need to be a third party. That reality is part of the difficulty of this situation. That is why we need an implementation period. We have in the political declaration a framework and in the business statements of the December Council a commitment. In “best endeavours”, we have something that gives legal force to ensuring momentum. It is a shared endeavour, too, because it is in neither side’s interests to trigger the backstop. There is, then, a mechanism, a framework and a process for addressing these concerns. The hon. Gentleman is absolutely right, however, that there is further significant work to be done, and that will be the job of this House.
