The Cost of Brexit: Is the UK Ready to Rejoin the EU?
The United Kingdom’s economy has shrunk by 4% to 8% of its GDP since leaving the European Union, according to the National Bureau of Economic Research (NBER), which estimates an annual cost of £180 billion. Current trends indicate a growing appetite for a “Swiss-style” economic reintegration with Brussels.
Why is the UK economy struggling post-Brexit?
The National Bureau of Economic Research (NBER) calculates that Brexit costs the UK approximately £180 billion (roughly €205 billion) every year. This economic drag has resulted in a total GDP loss ranging from 4% to 8%.
Beyond the balance sheets, the EU itself contracted. When the UK departed, the bloc dropped from 28 to 27 member states, losing 66 million citizens, which represented 13% of the EU’s total population.
Do Brexit voters regret the decision?
Public sentiment has shifted significantly. A poll by the European Council on Foreign Relations (ECFR), cited by the think tank Riparte l’Italia, shows that 66% of respondents link the rising cost of living to Brexit, while 65% point to negative impacts on the overall economy.

The data reveals a specific contradiction regarding immigration. While illegal immigration was a cornerstone of the “Leave” campaign, 56% of all respondents and 58% of those who originally voted for Brexit believe the move actually worsened the issue.
When asked about the primary advantages of leaving the EU, the most frequent response among those polled was “I don’t know.”
What is the “Swiss Model” and could it work for Britain?
Domhnall O’Sullivan of Swissinfo suggests the “Swiss model” is regaining traction as a viable path forward. Switzerland remains outside the EU but maintains deep trade and interaction agreements that provide economic benefits without full membership.
O’Sullivan notes that this approach, once discussed by right-wing figures like Nigel Farage, is now being proposed by left-wing strategists and the Financial Times. The goal is to maximize economic integration while minimizing the loss of national sovereignty.
However, this path faces internal resistance. The government must balance pressure from unions wanting closer EU ties against the Reform Party and “Brexiteers” who view any reintegration as a betrayal of the referendum.
How does “Manchesterism” change the economic approach?
Giuseppe Telesca of the University of Glasgow identifies a shift toward “Manchesterism,” a political course associated with Andy Burnham. This model promotes a “Productive State” where the government exerts public control over essential sectors.
Telesca explains that this approach targets services that private capital has failed to manage efficiently, specifically:
- Public transport
- Social housing
- Energy grids
- Water services
This strategy contrasts with the strict macroeconomic stability maintained by Chancellor Rachel Reeves. Telesca argues that while Reeves’ focus on balanced books is prudent, it has not yet sparked the necessary transformation of the British economy.
What role does US politics play in the UK-EU relationship?
The return of Donald Trump to the US presidency has accelerated the need for a UK-EU rapprochement. Giulia Caravale of Sapienza University of Rome notes that while Keir Starmer initially kept Brexit on the sidelines of his 2024 campaign to avoid division, external pressures are mounting.
Caravale argues that negative economic data and the shifting geopolitical landscape under the Trump administration are pushing the UK and EU toward a shared democratic value model. While Starmer has avoided pledging a return to the Single Market or Customs Union, the necessity of cooperation is increasing.
Mario Angiolillo, director of the Osservatorio Eu-Uk-Usa, adds that the timeline for this reunion will depend on global competition for rare earth minerals, energy security, and technological supremacy. He suggests that upcoming elections in key EU countries will ultimately dictate the terms of the rapprochement.
