The UK would vote to remain in the EU if a second Brexit referendum were held, according to a new polling analysis.
Peter Kellner, former president of YouGov and polling analyst, suggested that up to one million Labor supporters who voted Leave in the 2016 referendum are having second thoughts.
In an article for Prospect, Keller pointed out that YouGov carried out 14 polls this year asking people if the UK was right or wrong to vote for Brexit.
"Thirteen of 14 polls this year show slightly more people saying ‘wrong' than ‘right'," he said.
"This indicates a small but consistent net move away from Brexit."
A large part of Kellner's belief stems from data showing that generally older voters supported Leave, whereas younger voters tended to support Remain.
He said: "Bluntly, older, mainly Leave, voters are dying - and younger, mainly Remain, voters are joining the electorate."
Kellner pointed out that Leave voters outnumber Remain by 1.3 million and that since the referendum roughly 1.2 million voters had died, while 1.4 million have entered voting age, meaning "demography has already reduced that lead by more than half".
However, he warned that even if a second referendum were to take place, Labor would have to "campaign actively to stay in the EU".
"This would, of course, require Jeremy Corbyn to abandon his past views of Brussels, which have ranged from lack of enthusiasm to outright hostility," he added.
An exclusive survey for The Independent by BMG Research in December showed 51 per cent of people now backed remaining in the union, while 41 per cent still want Brexit.
Legal challenges also claimed another referendum is required before Britain can leave the EU.
