I am grateful to the Prime Minister for giving way—indeed, she is being very generous in giving way to a lot of people. We are told that the EU does not wish to exercise the backstop, Ireland does not wish to exercise it and certainly, the UK does not wish to exercise it. Is it not the case, therefore, that this is a matter not of renegotiating the withdrawal agreement, but of the European Union showing good will and good faith towards the United Kingdom by allowing us one additional line in the withdrawal agreement? This could be words to the effect that in the event of the backstop being triggered, the United Kingdom can, say, at three months’ notice, leave the customs union. To allow that one line would show enormous good faith and good will on the part of the EU, and nothing else.
