New polling analysis has suggested that the United Kingdom would vote to remain in the European Union if a second Brexit referendum were held today.

Up to one million Labour supporters who voted Leave in the 2016 referendum are having second thoughts, according to Peter Kellner, former president of YouGov and polling analyst.

“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.”

Meanwhile, an exclusive survey for The Independent by BMG Research in December showed 51% of people now backed remaining in the union, while 41% still want Brexit.

According to The Independent , legal challenges have also claimed another referendum is required before Britain can leave the EU.

The news comes as Michel Barnier, the chief Brexit negotiator for the EU, told Britain to “face the reality” of Brexit, and warned against blaming the EU for any negative consequences it caused.
