Perhaps I may continue. I recall no debate at all at the time of the referendum on a customs union. The country voted narrowly to leave the European Union, but no one can argue that it voted knowingly to leave the customs union with the European Union.
The red line was laid down in October 2016 in the “citizens of nowhere” speech. One hears that there had not been much discussion in the Government; there certainly had been no discussion with Parliament. One wonders to what extent the economic consequences of the decision on customs union had been fully assessed and analysed within the Government; I have no idea. Other red lines have since been sensibly blurred; in my view, it is time to blur this one.
The House knows that I was and remain a keen remainer. I believe that, when a deal is struck, the country should be given a chance to say whether it is what it wants. That would be fair, but it is nevertheless our duty to help improve the deal and see how it could be made better. If in the end we do leave, it should be in a way that limits the damage to the country’s well-being and to the future of our children. That is why I believe that it makes sense for the Government to be asked to explore customs union. I beg to move.
