United Kingdom voters are reflecting on the decision to leave the European Union on the 10th anniversary of the 2016 referendum [1].

This milestone marks a decade of political and economic transition for the UK. The widespread expression of regret suggests a significant shift in public sentiment regarding the country's sovereignty and its relationship with its closest neighbors.

Voters in England and Northern Ireland have expressed disappointment that the primary goals of the Leave campaign remain unfulfilled. Specifically, the promised freedom from EU laws, a reduction in immigration, and a significant economic boost have not been realized [2, 3]. These failures have led many who originally voted to leave to now view the decision as a mistake [2, 5].

In Northern Ireland, a majority of voters view the outcome of Brexit as a failure [4]. This sentiment reflects the unique complexities of the border and trade arrangements that followed the departure from the EU.

Public opinion remains divided on the overall success of the project. Some reports suggest that certain campaign claims have come true [6]. However, other polling indicates that a majority of Britons now believe Brexit was a mistake and would favor holding a new referendum [7].

The anniversary has highlighted a persistent bitterness over the vote [5]. While the legal process of leaving is complete, the social and economic fallout continues to shape the national discourse 10 years after the initial ballot [1].

The 10-year anniversary reveals a growing gap between the political rhetoric of the 2016 campaign and the lived economic reality of UK citizens. The emergence of 'Bregret' among former Leave voters suggests that the ideological appeal of sovereignty has been outweighed by the practical challenges of trade and immigration, potentially reopening the door for future political movements to advocate for a return to the EU.
