UK Can Avoid Euro But Must Accept Free Movement to Rejoin EU 2026

Michel Barnier, the EU's former chief Brexit negotiator, has confirmed that the UK can avoid adopting the euro but must accept free movement of people if it wants to rejoin the EU. In an interview with Sky News, Barnier said it would be "perfectly possible" to begin rejoin negotiations without an obligation to adopt the euro, directly contradicting claims by Reform UK leader Nigel Farage that the UK would be forced to sign up to the single currency.

The intervention comes as the debate over Brexit's economic damage intensifies, with a growing number of UK politicians and business leaders calling for a closer relationship with Brussels. Barnier's comments provide a significant boost to those arguing that rejoining is feasible without sacrificing key symbols of sovereignty like the pound.

Barnier Clarifies EU Stance on Euro and Free Movement

Barnier's remarks cut through years of misinformation about what EU membership entails. He explained that while new members are theoretically obliged to adopt the euro, the reality is far more flexible. Six of the EU's 27 member states do not use the euro, and Denmark has a formal opt-out. This precedent suggests the EU could easily grant the UK an opt-out as part of a rejoin deal.

However, Barnier was equally clear on free movement: it is a non-negotiable principle of the single market. Any country seeking full membership must accept the free movement of EU citizens. This is the core trade-off that Brexit supporters have long resisted, but it is also the key to unlocking the economic benefits of the single market.

Farage's Euro Claim Debunked by Former Negotiator

Nigel Farage has repeatedly claimed that rejoining the EU would force the UK to adopt the euro, using this as a scare tactic to undermine support for a reversal of Brexit. Barnier's comments directly refute this, exposing the claim as a myth designed to frighten voters rather than inform them.

The timing is notable: Farage is holding a press conference today, and reporters are likely to press him on his recent prediction that Trump would not "get smashed" in the US election—a prediction that proved spectacularly wrong. Now he faces another credibility test over his euro claim.

Why Free Movement Is the Real Sticking Point

While the euro issue is easily resolved, free movement remains the elephant in the room. For many Brexit voters, ending free movement was the primary motivation for leaving the EU. Rejoining would mean accepting it again, which is politically toxic in some parts of the country.

Yet the economic case for free movement is strong. Labour shortages in sectors like hospitality, agriculture, and healthcare have been exacerbated by the loss of EU workers. Businesses across the UK are struggling to fill vacancies, and the resulting wage inflation is contributing to persistent inflation.

The Economic Cost of Brexit Is Mounting

Barnier's intervention comes amid growing evidence of Brexit's economic damage. Trade barriers have hurt UK exporters, the pound has suffered, and investment has been diverted to the EU. The Office for Budget Responsibility estimates that Brexit will reduce long-run productivity by around 4% compared to staying in the EU.

As the damage accumulates, public opinion is shifting. Polls consistently show a majority of Britons now believe Brexit was a mistake, and support for rejoining is growing, especially among younger voters. Labour's landslide election victory has emboldened some within the party to advocate for a closer relationship with the EU.

What Rejoining Would Actually Look Like

Barnier's comments suggest a rejoin negotiation could be structured to accommodate UK red lines. The UK could keep the pound, maintain control of its borders in some form, and still gain access to the single market—though free movement would be part of the package.

This is not a simple return to the pre-2016 status quo. The EU has changed, and the UK would negotiate as a third country seeking to re-enter. But the precedent of Denmark's opt-out and the flexibility shown by Barnier indicate that creative solutions are possible.

What to Watch Next

Barnier's intervention is a reminder that the EU is open to a pragmatic deal. The ball is now in the UK's court. As politicians like Andy Burnham and Tony Blair push for a rejoin debate, the question is whether the British public is ready to accept free movement in exchange for economic prosperity.

The Brexit debate has been dominated by myths and misinformation for too long. Barnier's clarity on the euro and free movement is a step toward a more honest conversation. For a deeper analysis of the economic case, see our article on Brexit's economic damage and why the UK must rejoin the EU.

Meanwhile, the political landscape is shifting. Labour's leadership has been cautious, but figures like Andy Burnham are testing the waters. As we reported in Burnham's EU rejoin dream and Reynolds' cautious stance, the party remains divided on how far to go.

Public opinion will ultimately decide. Recent polling shows a majority support rejoining, but the intensity of that support varies. Our analysis of whether British voters are ready to rejoin the EU suggests the answer is yes, but with caveats.

High-profile figures are adding their voices. Tony Blair has argued for rejoining within the next decade, a position we examined in Tony Blair's call for Britain to rejoin the EU within the next decade. Blair's influence could shift the debate.

Andy Burnham has also made his position clear: the British public are the bosses. As we discussed in Burnham backs EU rejoin but says British public are bosses, this framing allows him to advocate for rejoin while respecting democratic legitimacy.

The debate is far from over, but the terms are becoming clearer. With each intervention, the path to rejoining becomes more defined. For a comprehensive overview of the key arguments, see our piece on the UK rejoin EU poll showing half of voters support return.
