Brexit at 10: Why Britain Remains Deeply Divided Over EU Exit

A decade after the historic 2016 referendum, the fallout from Britain's departure from the European Union continues to reshape the nation's political and economic landscape. While the legal process of leaving is complete, the promises made during the campaign are increasingly being weighed against a complex and challenging reality.

Economic Promises vs. The Reality of Trade Friction

The central ambition of the Brexit movement was to unlock economic growth by regaining sovereignty over policymaking and securing independent global trade deals. However, the economic boost envisioned by supporters has yet to materialize. Instead, British businesses are grappling with significant non-tariff barriers, including complex customs paperwork, stringent border checks, and new certification requirements when trading with the EU—Britain's largest trading partner.

Economists have been vocal about the long-term impact on the UK's GDP. Experts estimate that the British economy is currently between 4% and 8% smaller than it would have been had the country remained a member of the bloc. Jonathan Portes, a professor at King's College London, describes the impact not as a sudden collapse, but as a "gradual and cumulative drag" on the nation's trade, investment, and productivity. While many major deals, such as the long-awaited agreement with the United States, remain elusive, Brexit supporters maintain that the project must be judged over decades rather than years.

The Complex Shift in Immigration Patterns

Controlling borders was a cornerstone of the "Leave" campaign. While migration from EU member states has fallen sharply, the landscape of British migration has shifted rather than simply diminished. To address critical labour shortages in sectors like healthcare and elderly care, visa rules were adjusted, leading to an increase in arrivals from non-EU nations.

While net migration saw a significant drop from over 900,000 in 2023 to 171,000 last year, the political discourse has moved toward the arrival of asylum seekers via small boats across the English Channel. Despite these migrants representing only a fraction of total migration, the issue remains one of the most contentious and polarizing topics in British politics.

A Changing Political Landscape and Shifting Public Opinion

The political repercussions of Brexit have been profound, contributing to the end of 14 years of Conservative rule in 2024. While the current Labour government under Keir Starmer seeks a "reset" in relations with Brussels to reduce trade friction, they have firmly ruled out rejoining the EU or its single market.

Public sentiment also shows signs of a significant pivot. According to Ipsos surveys, 52% of Britons now support rejoining the EU, while only 33% oppose the idea. Furthermore, 48% of respondents believe Brexit has gone worse than expected, compared to a mere 9% who believe it has gone better. Despite this growing "Bregret," the path to reversing the decision remains politically fraught, as leaders struggle to balance democratic respect for the original vote with the economic necessity of closer ties to Europe.

Key Takeaways

• Economic Drag: Economists estimate the UK economy is 4% to 8% smaller due to Brexit, driven by trade friction and reduced productivity.
• Shifting Sentiment: Public opinion has turned, with 52% of Britons now supporting rejoining the EU and nearly half believing the exit has gone worse than expected.
• Political Deadlock: Despite the desire for closer ties, the Labour government has ruled out rejoining the EU, focusing instead on a pragmatic "reset" of relations.
