My hon. Friend makes an important point, highlighting one of the reasons why, when we published our Command Paper in the summer, we said that, as of then, the conditions to trigger article 16 had been met. We are very clear that we do not rule that out. If we have to use article 16, we will, but we are in negotiations with the European Union. The ideal solution for us would be to come to an agreement with the EU, but that has to be one that delivers on the needs of the people of Northern Ireland.
