I heartily welcome the Prime Minister’s firm assurances that any backstop will be temporary. Businesses that wish to trade outside ​the EU would like to plan for that event, and, in my opinion, they need to have an idea of how long the backstop would last. If the Prime Minister is not prepared to specify a date, will she tell us how we can shore up the fact that nothing can derail the temporary nature for which she wishes? May I also ask her to update the House on the future of British citizens in the EU during that temporary period?

As I have said to other Members, we are very clear that this should be temporary. As I said earlier, when we published the proposals for a UK-wide customs backstop, we included the expectation that it should end by December 2021, because the future economic relationship should be in place at that point. We are also clear about the fact that we cannot be in a position in which we would be potentially trapped in a permanent backstop, for a number of reasons, one of which is that we want to negotiate trade deals around the rest of the world and gain the economic advantage for this country of doing so.
