A new poll of 11,927 UK voters found that rejoining the European Union is the most popular policy option in 628 out of 632 parliamentary constituencies in Great Britain. The Multilevel Regression and Poststratification (MRP) analysis, conducted by YouGov and commissioned by the campaign group Best for Britain, showed that 35% of respondents favor full EU membership. This exceeded the 18% who support the government’s current position of closer ties within existing red lines and the 11% who favor loosening ties with the bloc.
The survey excluded the 18 constituencies in Northern Ireland. According to the data, EU membership was the top choice in every British nation and region, with support particularly concentrated in Scotland, which contains seven of the top ten ranking seats. Only four constituencies—Ashfield, Clacton, Great Yarmouth, and Boston and Skegness—did not list rejoining as the top choice; in those seats, "don't know" was the most frequent response. These four seats are currently held by Reform UK and Restore Britain.
The polling also assessed specific trade arrangements, finding that a "halfway house" approach lacked broad support. Only 6% of voters backed joining the single market, and 5% supported a customs union. Among supporters of specific political parties, 67% of Green Party voters, 56% of Liberal Democrat voters, and 55% of Labour voters preferred rejoining the EU. In the constituency of Bristol Central, support for membership was at its highest, while in Prime Minister Andy Burnham’s seat of Makerfield, 29% favored rejoining compared to 24% who answered "don't know."
The scale of the shift is further highlighted by polling expert Professor Sir John Curtice, who stated that 61% of Britons now favor rejoining the EU against 39% who wish to stay out. This represents the highest average level of support for rejoining since 2016. The polling suggests a gap between the current government policy of maintaining "red lines" and the specific preferences of a plurality of the electorate in nearly every constituency.
In the immediate term, these results place political pressure on Prime Minister Andy Burnham and the Labour government to reconsider their current stance on EU relations. While the government has stated it is building a relationship to "unlock good growth in every postcode," the poll indicates that voters may prefer a more formal integration than the current strategy allows. A UK-EU summit is scheduled for later this year, where the government intends to take further steps toward deepening ties.
On Friday, September 18, 2026, Prime Minister Burnham met with Irish counterpart Micheál Martin to push for deeper ties. A government spokesperson stated that the administration remains focused on an "ambitious, close relationship" to strengthen the economy. However, Liberal Democrat MP Christine Jardine cited the poll as evidence that Brexit was an "economic mistake" and called for closer alignment with European allies.
