It is not yet a treaty, if I can anticipate the noble Lord, Lord Foulkes, because the position of the EU has been, quite rightly, that there is no agreement until everything is agreed. This has been a staged process. We believe that it is important that we were able to achieve the first stage and that we were able to achieve consensus. It is perhaps better to use the word “consensus” here rather than “agreement”, which can be confusing and sometimes misleading. We have achieved consensus in a number of important areas and, as we carry that forward, we proceed into the negotiation of what will be an international treaty.
As we have said before, once we have that international treaty, we can then draw down from the rights and obligations of that international treaty into domestic law by virtue of the fact that we will bring forward a withdrawal agreement Bill for scrutiny by this Parliament.
