My Lords, at this hour, and given the debate, there will probably not be many Members of your Lordships’ House who are carefully weighing the arguments on either side, wanting to know what the Minister is going to say from the Dispatch Box that could just persuade them another way. We have been around this course many times and the arguments have not changed. The House knows the Government’s position on this: they have set it out many times. The people of the United Kingdom voted to leave the European Union and to take back control of their laws, borders and money, and have an independent trade policy. If we had a customs union, we would not get that. That is the central point against the amendment. On the other hand, we have a withdrawal agreement that allows us to have many of the benefits of our membership of the European Union without being members of it, and honours the referendum result.
I shall come to two points. The noble Lord, Lord Stevenson, when moving the amendment—which is worthy of further examination as to what it is seeking the Government to do—said that he wanted to give the other House an opportunity to think again on this issue. The noble Lord, Lord Kerr, in a brilliant, brief contribution—perhaps because we had heard his eloquence on this point in Committee—reminded the House that it voted in favour of his amendment. What they did not mention was that when it went to the other House, giving it an opportunity to think again, it rejected not only your Lordships’ amendment but the concept of a customs union put forward by Stephen Hammond when the Bill was at this stage in the other place. If the purpose is to give that House another opportunity to think again, perhaps it could shout down the Corridor, “We have already said it; did you not hear us the first time?”
Some noble Lords have pointed out that the uncertainty is damaging for business. I accept that. Uncertainty is always damaging for business. What business needs is certainty. However, right at the 11th hour, when we are within sight of and have an agreement, with an exit day that meets the criteria, the amendment proposes to require Her Majesty’s Government to reopen the whole negotiation process that has taken place over the past two years. Somehow that is supposed to help business. Not many businesses would sign up to that level of reopening negotiations and uncertainty. The presentation of the amendment presupposes that the outcome and benefits of a customs union are known. No—they would have to be negotiated. That would be the case unless, as the noble Baroness, Lady Falkner, rightly said, it actually related not to “a” but “the” customs union. In that case, the noble Lords’ option would be there immediately. That is the position of those who want to stay in the European Union, and we understand it.
The amendment therefore plunges us further back into uncertainty and more years of negotiation. The House has already given its view, not once but twice,
on this issue. The other place does not need the chance to think again and I therefore urge noble Lords to vote against the amendment if it is pushed to a Division. Most importantly, I urge all Members in the other place not to listen to the amendment but to look at the withdrawal agreement before them next week and make sure that they vote for it, so that we leave the European Union on 29 March, as the British people wanted, but with a deal.
