Brexit’s tenth anniversary reveals deep societal and political fractures in Britain

Ten years after the United Kingdom voted to leave the European Union, the political landscape remains defined by instability and deepening societal fractures. Prime Minister Keir Starmer has resigned, becoming the seventh British prime minister in a decade, a trend rooted in the political turmoil that began with David Cameron’s departure following the 2016 referendum. A YouGov survey conducted in June 2026 to mark the anniversary reveals that public sentiment has shifted dramatically, with just 30 per cent of Britons now believing leaving the EU was the right choice, down from 64 per cent in 2016. A clear majority of 57 per cent now consider the decision wrong, and six in ten judge Brexit as an outright failure.

While the Bank of England reports a 6 per cent contraction in the economy due to the departure, analysts argue that the most significant legacy is a coarsening of political discourse and a rise in exclusionary attitudes. The referendum normalised extreme rhetoric on immigration, transforming complex questions of sovereignty into a moralised debate on border control. This shift has elevated phrases and strategies once considered fringe, with successive governments competing to adopt tougher stances on migration, including offshore processing and schemes to deport asylum seekers to third countries.

The impact on social cohesion has been severe, with recent violence in Belfast highlighting the dangers of this polarised environment. Following a knife attack by a Sudanese national, masked crowds torched homes and businesses for several nights. Police had previously been warned about a "hit list" prepared by anti-immigration activists that targeted the same properties. This violence was not random but the culmination of months of targeted rhetoric that conflated refugees with criminals and framed minorities as threats to British values.

British Muslims have faced a disproportionate burden of this hostility, with discrimination affecting individuals regardless of their generation or status. The focus on migration has been used to brand Muslims as outsiders, a narrative reinforced by both mainstream political discourse and online disinformation campaigns. Experts note that the Brexit victory vindicated new approaches to information communication, where younger, tech-savvy strategists and bot farms bypass traditional media gatekeepers to spread disinformation and influence public opinion.

The political instability and social division continue to shape policy debates, with a resurgent Reform UK party under Nigel Farage ready to brand any concession to the EU as a betrayal. As the UK grapples with these unresolved issues, the decade since the referendum has left a legacy of eroded trust and increased vulnerability for minority communities. The focus on migration as a solution to socioeconomic grievances has coarsened the national conversation, posing a significant challenge to public democracy and social cohesion.
