A four-point surge in support for reversing the 2016 referendum means 53 per cent back membership in a survey by Savanta ComRes, with 47 per cent wanting to stay out of the EU.
One in ten Leave voters want to rejoin the bloc, as do one in five Conservative supporters, the poll found – while 40 per cent of adults back a fresh referendum within the next 5 years.
Strikingly, it is the second survey in recent days to have produced the same 6-point margin of favour of EU membership – nearly two years after Brexit was completed.
Savanta ComRes pointed to “momentum shifting towards a majority who would now vote to rejoin the EU”, despite no political party advocating the policy.
“Issues such as disrupted supply chains and spats with fellow European leaders over fishing and vaccines may have cut through, although the results are still on a knife-edge,” said research director Chris Hopkins.
He pointed to the 77 per cent of 18 to 34-year-olds who support rejoining – and no less than 80 per cent of those who failed to vote in 2016, adding: “The Brexit story isn’t going away any time soon.
“All eyes will be on those who did not vote in 2016 and younger voters who may have not had the opportunity to, who are both overwhelmingly in favour of the UK becoming a member again.”
Ministers were also forced to concede that Brexit was a key cause behind the autumn food and fuel shortages – which have put Christmas deliveries at risk.
