Britain’s Brexit point man says no to rejoining EU customs union

BRUSSELS — Britain’s top Europe minister defended a decision to keep the U.K. out of the EU’s customs union — despite sounding bullish on a speedy reset of ties with the bloc in the first half of 2026.

Speaking to POLITICO in Brussels where he was attending talks with Maroš Šefčovič, the EU trade commissioner, Nick Thomas-Symonds said a non-binding British parliamentary vote on Tuesday on rejoining the tariff-free union — pushed by the Liberal Democrats, but supported by more than a dozen Labour MPs — risked reviving bitter arguments about Brexit.

Thomas-Symonds described the gambit by the Lib Dems — which had the backing of one of Labour’s most senior backbenchers, Meg Hillier — as “Brexit Redux.” And he accused Ed Davey, the Lib Dem leader, of wanting “to go back to the arguments of the past.”

The Lib Dems have drawn support from disillusioned Labour voters, partly inspired by the party’s more forthright position on moving closer to the EU. But Thomas-Symonds defended Labour’s manifesto commitment to remain outside the single market and the customs union.

“The strategy that I and the government have been pursuing is based on our mandate from the general election of 2024, that we would not go back to freedom of movement, we would not go back to the customs union or the single market,” the British minister for European Union relations said.

Thomas-Symonds said this remained a “forward-looking, ruthlessly pragmatic approach” that is “rooted in the challenges that Britain has in the mid 2020s.” He pointed out that post-Brexit Britain outside of the customs union has signed trade deals with India and the United States, demonstrating the “advantages of the negotiating freedoms Britain has outside the EU.”

‘Get on with it’

Speaking to POLITICO’s Anne McElvoy for the “Politics at Sam and Anne’s” podcast, out on Thursday, Thomas-Symonds was optimistic that a grand “reset” of U.K.-EU relations would progress more quickly in the new year.

The two sides are trying to make headway on a host of areas including a youth mobility scheme and easing post-Brexit restrictions on food and drink exports.

“I think if you look at the balance of the package and what I’m talking about in terms of the objective on the food and drink agreement, I think you can see a general timetable across this whole package,” he said. Pressed on whether this could happen in the first half of 2026,  the U.K. minister sounded upbeat: “I think the message from both of us to our teams will be to get on with it.”

 The Brussels visit comes after talks over Britain’s potential entry into a major EU defense program known as SAFE broke down amid disagreement over how much money the U.K. would pay for access to the loans-for-arms scheme. The program is aimed at re-arming Europe more speedily to face the threat from Russia.

Asked if the collapse of those talks showed the U.K. had miscalculated its ability to gain support in a crucial area of re-connection, Thomas-Symonds replied: “We do always impose a very strict value for money. What we would not do is contribute at a level that isn’t in our national interest.”

The issued had “not affected the forward momentum in terms of the rest of the negotiation,” he stressed.

Youth mobility standoff

Thomas-Symonds is a close ally of Prime Minister Keir Starmer and has emboldened the under-fire British leader to foreground his pro-Europe credentials.

The minister for European relations suggested his own elevation in the British government — he will now attend Cabinet on a permanent basis — was a sign of Starmer’s intent to focus on closer relations with Europe and tap into regret over a post-Brexit loss of business opportunities to the U.K.

Fleshing out the details of a “youth mobility” scheme — which would allow young people from the EU and the U.K. to spend time studying, traveling, or working in each other’s countries — has been an insistent demand of EU countries, notably Germany and the Netherlands.

Yet progress has foundered over how to prevent the scheme being regarded  as a back-door for immigration to the U.K. — and how exactly any restrictions on numbers might be set and implemented.

Speaking to POLITICO, Thomas-Symonds hinted at British impatience to proceed with the program, while stressing: “It has to be capped, time-limited, and  it’ll be a visa-operated scheme.

“Those are really important features, but I sometimes think on this you can end up having very dry discussion about the design when actually this is a real opportunity for young Brits and for young Europeans to live, work, study, enjoy other cultures.”

The British government is sensitive to the charge that the main beneficiaries of the scheme will be students or better-off youngsters. “I’m actually really excited about this,” Thomas-Symonds said, citing his own working-class background and adding that he would have benefited from a chance to spend time abroad as a young man “And the thing that strikes me as well is making sure this is accessible to people from all different backgrounds,” he said.

Details however still appear contentious: The EU’s position remains that the scheme should not be capped but should have a break clause in the event of a surge in numbers. Berlin in particular has been reluctant to accept the Starmer government’s worries that the arrangement might be seen as adding to U.K. immigration figures, arguing that British students who are outside many previous exchange programs would also be net beneficiaries. 

Thomas-Symonds did not deny a stand-off, saying: “When there are ongoing talks about particular issues, I very much respect the confidentiality and trust on the ongoing talks.” 

Britain’s most senior foreign minister, Yvette Cooper, on Wednesday backed a hard cap on the number of people coming in under a youth mobility scheme. She told POLITICO in a separate interview that such a scheme needs to be “balanced.”

“The UK-EU relationship is really important and is being reset, and we’re seeing cooperation around a whole series of different things,” she said. We also, at the same time, need to make sure that issues around migration are always properly managed and controlled.” A U.K. official later clarified that Cooper is keen to see an overall cap on numbers.

Boozy gift

As negotiations move from the technical to the political level this week, Thomas-Symonds sketched out plans for a fresh Britain-EU summit in Brussels when the time is right. “In terms of the date, I just want to make sure that we have made sufficient progress, to demonstrate that progress in a summit,” Nick Thomas-Symonds said.

“I think that the original [post-Brexit] Trade and Cooperation Agreement did not cover services in the way that it should have done,” he added. “We want to move forward on things like mutual recognition of professional qualifications.”

Thomas-Symonds, one of the government’s most ardent pro-Europeans, meanwhile told POLITICO he had forged a good relationship with “Maroš” (Šefčovič) – and had even brought him a Christmas present of a bottle of House of Commons whisky. “So there’s no doubt that there is that trajectory of closer U.K.-EU cooperation,” he quipped.
