New polling data indicates that the majority of parliamentary constituencies across Great Britain would support reversing Brexit and rejoining the European Union. The survey, which involved interviews with 11,927 voters across 632 constituencies (excluding Northern Ireland), found that 35 percent of respondents favored restoring EU membership as the preferred government policy regarding the UK’s relationship with the bloc.

The poll, commissioned by Best for Britain and conducted by YouGov, revealed EU membership as the most popular option in almost every constituency except for four seats—Ashfield, Clacton, Great Yarmouth, and Boston and Skegness—where the most common response was “don’t know.” These seats are held by Reform UK and Restore Britain, parties known for their Eurosceptic positions. Other policy options, such as maintaining the government’s current approach of seeking a closer relationship with the EU within existing red lines, received backing from 18 percent of respondents. Meanwhile, loosening ties with the EU was preferred by just 11 percent of voters. More moderate positions like joining the single market or a customs union were the least popular, with only six and five percent support, respectively.

The polling results come amid growing calls within some political circles to reconsider the UK’s post-Brexit stance toward Europe. Andy Burnham, the Labour mayor of Greater Manchester, has expressed support for fostering a “deeper relationship” with the EU, aiming to attract voters by emphasizing closer ties. The findings present potential pressure on the Labour Party and other politicians to rethink their positions on EU relations ahead of the next general election. Tom Brufatto, policy and research director at Best for Britain, commented that the survey offers a pathway for progressive parties to connect with voters and counter the influence of radical right groups, pointing to research suggesting that rejoining the EU could boost the UK economy by approximately £92 billion.

Support for rejoining the EU was strongest among voters who identify with Labour, Liberal Democrat, and Green parties, with 55 percent, 56 percent, and 67 percent respectively favoring membership restoration. Geographically, Scotland showed particularly strong support, with seven of the top ten constituencies favoring EU membership located there. The constituency with the highest level of support was Bristol Central. In Burnham’s own seat of Makerfield, nearly 30 percent of respondents selected returning to EU membership as their preferred option.

Liberal Democrat MP Christine Jardine described the poll as evidence that Brexit was a “massive economic mistake” and called for a political response to repair its impacts by strengthening ties with European allies, a move she argued is essential for the UK’s stability and security.

The UK government responded by reaffirming its commitment to building an “ambitious, close relationship” with the EU that supports economic growth across the country, emphasizing ongoing diplomatic efforts, including recent talks between the UK Prime Minister and Ireland’s Taoiseach Micheál Martin. The Prime Minister highlighted the intention for a “stronger and closer” relationship with the EU, with plans for a UK-EU summit later in the year during Ireland’s EU presidency.

Meanwhile, political analysts note that public support for rejoining the EU is at its highest point since the 2016 referendum. However, experts caution that this shift in opinion will require proactive leadership from political parties to translate into policy change. Without such engagement, the opportunity to realign the UK’s relationship with the EU may not materialize.
