More UK voters now think it was wrong to back Brexit for the first since the EU referendum, a YouGov poll published on Thursday 27 April has revealed.
The survey for The Times, of more than 1,500 people between 25 and 26 April, found that 45% (+2) of respondents oppose the Leave vote, whilst 43% (-3) of the public still think it was the right decision.
The research comes 10 months after the Brexit vote and just one month after Prime Minister Theresa May invoked Article 50 of the Lisbon Treaty, triggering two-year-long divorce talks with Brussels.
The Conservative premier used the major issue to call a snap general election on 8 June, warning that Westminster was divided over Brexit.
"We need a general election and we need one now because we have at this moment a one-off chance to get this done while the European Union agrees its negotiating position and before the detailed talks begin," she said outside of Number 10 Downing Street.
The decision also means that May is on course to dramatically increase her working majority of 17 MPs in the House of Commons. YouGov put the Conservatives on a 16-point lead over Labour (45% versus 29%).
But the Liberal Democrats are hoping to take seats from the Tories with their pro-EU message. Tim Farron's party is currently polling at 10%, up three points on their 2015 general election performance.
Labour, meanwhile, have promised to respect the Brexit vote. But Shadow Brexit Secretary Sir Keir Starmer said the party would rip up the government's White Paper and immediately guarantee the residency rights of the more than three million EU nationals living in the UK.
