My Lords, I support Amendment 1, moved so persuasively by the noble Lord, Lord Kerr, and Amendment 4. I want to speak briefly to Amendments 2 and 5 in my name, which are coupled with them and essentially seek the same goal.
Noble Lords may remember that in Committee I moved the very first amendment on the issue of maintaining a customs union with the EU after our membership ceases. We had an excellent debate at that stage so I will not repeat the detailed arguments, save to remind the House of one central point: having tariff-free trade in goods with the European Union and the 56 countries with which the European Union has an agreement is fundamentally important—not only to Wales but throughout the UK—to our manufacturers and farmers. It also opens the door to resolving the Irish border question, as has been said.
I accept—reluctantly—that we are leaving the European Union. That is not the issue in this debate. The question is how we leave without weakening or severing our vital trade links. By passing either of these amendments, we give MPs an opportunity to return to this central issue. Without such an amendment, they will be unable to do so. They need such a facility because so much has changed in the time that has elapsed since they passed this Bill last year. We must enable them to fine-tune the Bill to meet the requirements of exporters, manufacturers and farmers. MPs will have the last word, and rightly so, but by passing either amendment we give them the opportunity to endorse a better Bill that is fit for purpose and more acceptable to those whom it affects. I urge colleagues on all sides to unite in passing such an amendment and I urge the Government to accept the outcome.
