The right hon. Gentleman started in a welcome tone of offering cross-party collaboration. I was waiting to see what he proposed as the starting point for the Labour party. He spent about 30 seconds on that, in a couple of sentences, and he is now back to attacking the Government and the withdrawal agreement. Am I right in understanding that he essentially agrees with me that we should stay in a customs union and collaborate with our European partners on international trade deals? He talked about us collaborating with the single market, which I do not quite understand. Nowhere in the world is there an open border between two countries unless they have a customs union and regulatory convergence. Is he advocating that? That not only solves the Irish border problem, but eases the economic consequences of leaving the European Union to a considerable extent.
