Windsor Framework: Internal Market Guarantee

Carla Lockhart Excerpts

Wednesday 10th September 2025 Westminster Hall

[The Paymaster General and Minister for the Cabinet Office (Nick Thomas-Symonds)]

It is a pleasure to serve under your chairmanship, I think for the first time, Dr Allin-Khan. I congratulate the hon. and learned Member for North Antrim (Jim Allister) on securing this debate, and I thank the other Members for their interventions. He has also asked me questions in the main Chamber a number of times, and he always makes his case powerfully. He and I share a background in law—we were barristers before becoming Members of Parliament—so I recognise how he structures his argument effectively.

I begin with the things on which we agree, and I will leave it to the hon. and learned Gentleman to judge at the end of the debate whether my language is “dressing up”. We agree on the importance of protecting Northern Ireland’s integral place in the UK’s internal market, and I repeat my commitment to that endeavour today. That is every bit as sincere as the commitment I made to stakeholders across Northern Ireland when I visited. I have great affection for Northern Ireland. When I came into this job, an early priority of mine was to visit Belfast to speak to politicians, visit the Assembly and speak to businesses and people across Northern Ireland.

Yes, of course I speak today as a Minister in the Government, but it is also my great privilege to serve as Member of Parliament for Torfaen. Serving as a Welsh Member of Parliament only adds to my conviction that our nations of this United Kingdom stand to achieve far more economically, socially and culturally by working together than we would ever achieve alone.

I say directly to the hon. and learned Member, and indeed to all those who have intervened today, that this Government’s commitment to the UK internal market is not a vague concept or an aspiration; it is real.

[Carla Lockhart (Upper Bann) (DUP)]

I thank the right hon. Member for giving way and for his engagement on this issue. I wrote to him at the beginning of the year, asking him to come to hear directly from businesses in Upper Bann. The offer was declined, but he kindly sent officials along.

The impact was laid bare at the meeting with those officials last week by used agricultural machinery folks, by small retailers who are impacted by the parcels border, and by agrifood businesses. Each business around the table noted the diversion of trade. Today, we are alerting the Minister to the diversion of trade. What is he doing about it? There is anecdotal evidence from each of those businesses, but there is also evidence from the Northern Ireland Statistics and Research Agency that the proportion of GB manufacturing selling to Northern Ireland has reduced from 20.1% to 12.9%. We need action, and we need it now.

[Nick Thomas-Symonds]

I will certainly be visiting Northern Ireland again. However, on the diversion of trade, that is precisely what the independent monitoring panel is currently looking at. The panel is looking at it for the earlier part of this year, and I expect it to report shortly. Of course, when the panel makes recommendations, where there are issues, the Government will consider them very carefully.

The Government’s commitment to the UK internal market is in our manifesto. It is set out in law, in section 46 of the United Kingdom Internal Market Act 2020, which, to respond to the point made by the hon. and learned Member for North Antrim, also explicitly provides that Northern Ireland is part of the UK’s customs territory. As I say, this issue is not just about the guarantee, important though that is; it is also important that the independent monitoring panel does its work.

I also have to say that the position of Northern Ireland has always been at the forefront of my mind when I have negotiated with the European Union. The hon. and learned Member talks about checks on the Irish sea. Of course, it is the case that this Government will implement the Windsor framework in good faith. Indeed, I give credit to the previous Government for negotiating the Windsor framework. We supported it in opposition, and we have implemented it.

Of course, the purpose of what I have been doing is, far from increasing checks on the Irish sea, to reduce them. That is what a sanitary and phytosanitary agreement will do, once we are able to implement it. In a speech I made in recent weeks, I said that I want to see the SPS agreement in place by early 2027. That will have the effect of reducing precisely the kind of checks that the hon. and learned Member has been referring to.
