UK public support for rejoining EU grows as majority label Brexit failure

Public sentiment regarding the United Kingdom’s departure from the European Union has undergone a fundamental transformation, with a clear majority of voters now categorising the 2016 exit as a failure. Ten years after the historic referendum, recent polling data indicates that the demographic shift caused by the passing of older voters and the maturation of younger cohorts has resulted in a consistent public preference for closer ties to the continent, with significant support for eventual re-entry into the European Union.

According to surveys conducted by YouGov and other independent bodies, roughly 54% of the British public now view the decision to leave the bloc as a mistake. This represents a widening margin of dissatisfaction that has been tracked consistently since 2019. Further research commissioned by the European Council on Foreign Relations (ECFR) revealed that 52% of voters would choose to rejoin the European Union if a referendum were held today, while only 31% would opt to remain outside the bloc.

Generational Divide and Demographic Shifts

The desire for a return to the European fold is most pronounced among younger Britons. Data from a study by the thinktank More in Common highlights that 60% of individuals aged 18 to 28 would support rejoining the European Union. Among this cohort, support rises to 81% when filtering for likely voters in a hypothetical second referendum. Younger voters frequently cite the formative nature of the 2016 campaign on their political upbringing, yet many express frustration that the ensuing decade of debate has distracted from pressing issues such as the cost of living, housing, and climate change.

This demographic trend is underpinned by significant changes in the electorate. As noted by pollster Peter Kellner, approximately 6 million voters who were eligible in 2016 have since died, while another 6 million young people have entered the voting population. Because older demographics in 2016 were statistically more likely to vote for Brexit, this mortality-driven turnover has eroded the original pro-Leave majority.

Shifting Policy Priorities

Despite the growing desire for rejoining, appetite for an immediate, divisive referendum remains limited. Only 11% of the public identify EU membership as a top political priority, and 52% oppose the prospect of another vote. Most Britons appear to hold a sense of "political fatalism," acknowledging the perceived failure of Brexit while fearing the return of the national "psychodrama" that defined the transition years.

The UK government, currently navigating a "reset" of diplomatic ties, has maintained strict parameters regarding the scope of cooperation. During the lead-up to the 22 July 2026 UK-EU Summit, officials have clarified that there are no plans to re-enter the customs union, the single market, or to restore freedom of movement. Prime Minister Keir Starmer has emphasized that the government's focus is on legislative alignment to reduce trade burdens and lower prices, rather than a return to full membership.

Cross-Party Realignment

While the Conservative Party maintains that leaving the EU was a legitimate democratic outcome that secured sovereignty, and Reform UK continues to advocate for further distance from Brussels, the broader political consensus is shifting. ECFR polling indicates that even among 2016 Leave voters, there is a majority sentiment—66%—that supports closer economic ties with the EU.

The economic impact remains a primary driver of this sentiment. Independent studies, including reports cited by the UK government, suggest that Brexit has contributed to higher costs for businesses, increased food prices, and reduced productivity. Data analyzed by researchers suggests that the UK economy took a 6% hit due to the transition, with some devolved nations, such as Scotland, suffering significantly in key export sectors like food, whisky, and professional services.

What to Watch Next

• 22 July 2026: The upcoming UK-EU Summit, where the government aims to finalize an ambitious package of trade and cooperation deals, including a proposed Sanitary and Phytosanitary (SPS) Zone to reduce red tape.
• Legislative Alignment: Ongoing parliamentary debates regarding "dynamic alignment" and how much authority ministers will have to match EU rules without primary parliamentary votes.

As the anniversary of the referendum passes, the focus for many in Westminster and beyond is not on relitigating 2016, but on how to manage a future where the UK’s economic and security interests are increasingly perceived as inextricably linked to those of its immediate neighbors. Whether this public desire for a "European future" leads to a formal application for membership remains the defining, yet currently dormant, question of the era.
