Research suggests 2.6 million people who voted for Brexit in 2016 now want to stay in the European Union.

Those calling for a second referendum on leaving the EU say enough people have switched from supporting Leave to supporting Remain that it would overturn the 2016 result.

The findings came from two polls of more than 15,000 people taken before and after Theresa May revealed her controversial Chequers plan for Brexit.

Best for Britain and Hope not Hate commissioned analysis of the two YouGov polls and found that one million Remain voters now back Brexit.

That means an overall switch of 1.6 million people who first voted Leave but now want to stay in the EU.

Labour MP David Lammy, a prominent supporter of Best for Britain, said: ‘After two years of stalling negotiations, job losses and skills shortages in the NHS, millions more voters have seen through the lies of Brexit.

‘With the Tory government in the pocket of its hard right fringes, it’s up to Labour to give these voters a voice.

Why having a disposable barbecue on wooden decking isn’t the best idea‘Labour members, Labour voters and many Labour MPs remain strongly pro-European.

‘Our leadership needs to wake up and smell the coffee, by supporting a people’s vote on the final deal.’

Best for Britain chief executive Eloise Todd said: ‘This data shows the tide is turning on Brexit. People want to have the final say on whether we leave Europe or not.’

The pro-Remain group has launched a £200,000 publicity campaign calling for an ’emergency stop button’ to halt Brexit.
