I was astonished to hear my right hon. Friend agree that we would be perfectly all right to proceed on WTO rules. Does he accept that WTO rules will require the European Union to apply tariffs against our agriculture, fisheries and much of our manufacturing, in line with the tariffs it imposes against other third-party countries, and that WTO rules will require us to have a closed border in Ireland to enforce those restrictions? We cannot have it one way and another: we either obey the WTO rules or we ignore those as well and pretend we are going into some never-never land, but my right hon. Friend cannot simply accept calmly the argument that WTO rules would do no damage to our economy.
