The Northern Ireland Statistics and Research Agency states that only 5% of Northern Ireland’s sales cross the border south and only 1.6% of the Republic’s exports go north. The Government paper, confirmed by the head of Her Majesty’s Revenue and Customs, says that that is easily surmountable without a hard border. The Belfast agreement confirmed Northern Ireland as an integral part of the United Kingdom with standard regulation throughout. We are going to leave the single market and the customs union. Will the Secretary of State confirm that this week the integrity of the United Kingdom comes first, and that, if necessary, no deal is better than a bad deal?
