As of June 2026, 57 percent of people in Great Britain thought that it was wrong to leave the European Union, compared with 30 percent who thought it was the right decision. During this time period, the share of people who regret Brexit has been slightly higher than those who support it, except for some polls in Spring 2021, which showed higher levels of support for Brexit. 

Is Bregret setting in?

Since late July 2022, the share of people who regret Brexit in these surveys has consistently been above 50 percent. Additionally, a survey from January 2025 highlighted that most people in the UK thought that Brexit had had a mainly negative impact, especially on the cost of living and the economy. Despite there being a clear majority of voters who now regret Brexit, there is as yet no particular future relationship with the EU that has overwhelming support. As of late 2023, 31 percent of Britons wanted to rejoin the EU, while 30 percent merely wanted to improve trade relations and not rejoin either the EU or the single market.

Leave victory in 2016 defied the polls

In the actual referendum, which took place on June 23, 2016, Leave won 51.9 percent of the votes and Remain 48.1 percent, after several polls in the run-up to the referendum put Remain slightly ahead. Remain were anticipated to win until early results from North East England suggested that Leave had performed far better than expected, with this pattern replicated throughout the country. This event was repeated somewhat in the U.S. election of that year, which saw Donald Trump win several key swing states such as Pennsylvania and Wisconsin, despite predictions that these states would vote for Hillary Clinton.
