I will begin by answering my right hon. and learned Friend Mr Clarke, who said that he had not heard a single argument against a customs union. I credit him for staying for the whole debate, because I am going to give him plenty. He also said that I had been involved in a filibuster, but my contribution to the business of the House motion lasted for one minute and 13 seconds. That must be the shortest filibuster that there has ever been. I did once speak for one hour and 43 minutes on beer duty, but I do not think that one minute and 13 seconds really counts.
Why is a customs union a very bad idea? Broadly speaking, it would mean a huge loss of control over our economic policy, a decline in our foreign policy influence and a huge democratic deficit. Trade policy is not just about trade deals. It is about much more, which we would be handing over to the European Union without a seat at the table. There are tariffs, remedies and preferences as well as trade agreements, and these would all be given over. The House of Commons would abrogate its responsibility in relation to the UK’s trade policy. This is not Andorra or San Marino, which are currently in customs unions with the European Union. This is the world’s fifth largest economy.
My right hon. and learned Friend the Member for Rushcliffe and I were on the same side in the referendum in 2016, so I am approaching this debate not as some kind of Brexiteer, but from the position of what makes sense for the UK’s trade policy. It makes no sense in our democracy for the House of Commons to vote tonight to hand over control of UK trade policy to Brussels. It would mean that a Maltese Commissioner, a Latvian MEP, a Portuguese Commissioner and a Slovene MEP would all have more say over UK trade policy than any elected politician, including the UK Prime Minister. That is not democratically sustainable, nor is it sustainable for our foreign policy.
My right hon. and learned Friend and I served in the Government together. At that time, I went into various rooms in foreign countries to speak to foreign Governments, so I know that trade is one of the aspects of leverage that we have. As a member of the European Union, the UK has influence on EU trade policy. That will obviously be gone when we are no longer a member, but under a customs union we would also have no influence over our own trade policy. We would be unable to have those conversations with the Government of the United States when we can say, “Well, if we can do this on some other area, we will have a word in Brussels on this particular trade issue.” All of that would be gone.
