I thank the Prime Minister for giving way. As she knows, many of us would have preferred a circumstance where we could unilaterally have withdrawn from this agreement, and that does not apply after what the Attorney General said earlier. That means that we are going into a circumstance where there will be a deal of trust over how we resolve the backstop and, in particular, over whether the alternative arrangements prove acceptable to the European Union and the Republic of Ireland. Some of those alternative arrangements have previously been rejected by the Union and the Republic of Ireland. Has the Prime Minister detected any change in mood on the part of the Union and the Republic with respect to a constructive outcome to dealing with the Northern Ireland border?
