Two-thirds Of Londoners Would Vote To Rejoin EU, Poll Finds

Support for reversing Brexit has reached 67% in the capital, with younger adults overwhelmingly in favour. The findings increase pressure on Prime Minister Andy Burnham to set out how far his promised reset with Europe will go.

Two-thirds of Londoners would vote for the UK to rejoin the European Union if a referendum were held tomorrow, according to new polling that shows the capital moving further towards Europe a decade after the Brexit vote.

The Savanta survey for Queen Mary University of London’s Mile End Institute put support for rejoining at 67%, against 33% who would vote to remain outside the bloc. Savanta’s published methodology says 1,036 London adults were interviewed online between 30 June and 8 July 2026, with the results weighted to represent the capital’s adult population.

Backing was strongest among younger Londoners. Some 82% of respondents aged 18 to 24 supported rejoining, rising to 86% among those aged 25 to 34. Support stood at 71% among 35 to 44-year-olds, 60% among people aged 45 to 54 and 50% among those aged 55 and over.

The geographical divide was also significant. Rejoining was supported by 79% of respondents in north London and 72% in central boroughs, compared with 68% in east London and 60% in both the south and west. Women backed returning to the EU by 71%, against 63% of men.

London Support Has Risen Since The 2016 Vote

London was the only English region to vote Remain in the 2016 referendum, when 59.9% supported continued EU membership and 40.1% voted Leave.

The new figure is about seven percentage points higher, although the comparison is not exact: the earlier result was an actual referendum on staying in the EU, while the Savanta finding measures voting intention in a hypothetical contest about rejoining.

The capital is also more strongly pro-rejoin than Britain as a whole. YouGov polling conducted in June found that 55% of Britons supported EU membership, while 34% opposed it.

However, support fell to 35% when respondents were told the UK might have to return without its former opt-outs, including special arrangements concerning the euro and the Schengen area. Opposition under those conditions rose to 43%.

That distinction matters because any future membership application would require negotiations with EU institutions and all member states. The London result demonstrates substantial support for the principle of rejoining, but does not by itself establish which membership terms voters would accept.

Burnham Promises Closer Ties But Not Re-entry

The findings place the issue before Andy Burnham during his first weeks as prime minister. Burnham entered Downing Street on 20 July 2026 after returning to Parliament and becoming Labour leader, according to the government’s official ministerial record.

In May, Burnham said he was not proposing that Britain rejoin the EU, although he described Brexit as economically damaging. Since becoming prime minister, he has instead committed to a “closer and ambitious” relationship with Europe and agreed with European leaders to work towards a UK-EU summit later in 2026.

Sir Sadiq Khan has taken a more explicit position, arguing that Labour should ultimately seek a mandate to rejoin. City Hall has cited Cambridge Econometrics analysis estimating that London’s economy was more than £30 billion smaller in 2023 than under a scenario in which Britain had remained in the single market and customs union.

That figure is a modelled estimate rather than a direct measurement, but it has become central to the mayor’s economic case for closer integration.

The next confirmed test of Burnham’s approach will be the planned UK-EU summit. For now, the government is promising deeper co-operation on growth, defence and security, while stopping short of adopting the rejoin policy supported by most Londoners in the new poll.
