Absolutely. We will not debate the constitutional history, but people are trying to invoke the strictest interpretation of Standing Orders going back to attempts in the late 19th century to stop the Irish nationalists filibustering, which brought the whole thing grinding to a halt. Now we are saying that as this Parliament has the temerity to have a range of views, some of which are not acceptable to the Government, Standing Orders should be invoked against us to discipline us. Anyway, I will not go back to that, but I agree with my right hon. Friend.
The other thing that I shall vote for is another thing that supports the Prime Minister’s stated ambition for the long-term future of the country: open borders and free trade between ourselves and our markets in the EU, as demanded by our business leaders, our trade union leaders, and, I think, most people who have the economic wellbeing of future generations at heart. I think the only known way in the world in which we can do that is to stay in a customs union, and also to have sufficient regulatory alignment to eliminate the need for border barriers. I do not mind if some of my right hon. and hon. Friends prefer to call the customs union a “customs arrangement” or if they care to call the single market “regulatory alignment”. I do not feel any great distress at their use of gentler language to describe these things. Nevertheless, something very near to that is required to deliver our economic and political ambitions.
It is also the obvious and only way to protect the permanent open border in Ireland. We do not need to invent this ridiculous Irish backstop if the whole United Kingdom is going into a situation where it has an open border with the whole of the European Union in any event. The Irish backstop was only invented to appease those people who envisaged the rest of the British Isles suddenly deciding to leave with no deal before we had finished the negotiations in Europe. Well, let us forget that. Let us make it our aim—it will not be easy but it is perfectly possible—to negotiate, probably successfully, with the other 27 an open trading economic and investment relationship through the single market and the customs union.
