European Union (Withdrawal Arrangements) Bill

I very much like the image of the law of unintended consequences poking its head around the door. One thing that has occurred to me during this debate is that we need, in Northern Ireland and Great Britain and the whole of our United Kingdom, to try to reduce the red tape that Brexit has introduced. One of the most important steps that we could take is to enter into a sanitary and phytosanitary agreement with the European Union, but if we are to do that, we will need the EU to trust us, and to accept that if we negotiate with it and reach an agreement, we will stick by that agreement. Is not the challenge, in the context of this particular Bill, that one of the laws of unintended consequences might be that the EU simply will not engage in the discussion and negotiation that we need in order to proceed with those red-tape-reducing measures?
