I am grateful for that intervention. One of the central problems in all this is that the political declaration is 26 pages long, it is vague in the extreme and simply talks about a “spectrum” of outcomes. The main theme of the political declaration is that the extent of any checks at borders will depend on the degree of alignment; therefore, there is a spectrum of outcomes. I think that we all understood that within hours of the referendum. That is why there is all this pressure on the backstop—because the political declaration is so ill-defined.
