My Lords, the purpose of the amendment is to give the other place a chance to consider whether the UK should seek to remain in a customs union with the EU. It is an option that we know is realistic and negotiable, as signalled by senior EU figures over recent weeks and months. It has demonstrable support among communities throughout the United Kingdom, this House and the Commons, as well as business and trade unions, and would go a very long way to providing a permanent solution for Northern Ireland.
A customs union with the EU would guarantee continued UK access to existing EU trade agreements without having to roll over after 29 March, although that does not seem to be going terribly well. It would enable the UK to have a say on the direction of future European trade negotiations, allowing us to push forward our principles of development and strong standards, and our values in tackling issues such as climate change. It would offer certainty and stability to British industry, thereby protecting jobs and allowing businesses to secure new trading opportunities. When coupled with a close single market relationship, it would create the conditions for our vital services economy—80% of our GDP—to flourish and grow. The other place narrowly rejected a customs union when it considered the Bill, in part because the Prime Minister promised to replicate the benefits in her deal. However, they are for negotiation and certainly not yet agreed.
If this House supports the amendment, we are doing our duty in allowing the Commons to think again about a really important issue. I beg to move.
