The first signs that Britons are regretting voting for Brexit are revealed in a major poll for the Mirror today.

The survey finds that if the EU referendum were held again the result would be reversed with 51% voting for Remain and 49% to leave.

It also shows that people are less positive about leaving the EU since Theresa May’s speech outlining plans for a hard Brexit .

The Google survey of more than 44,000 readers of Mirror websites reveals that 13.5% of people who voted “out” would vote “in” if there were a second referendum.

By contrast 9.3% of people who voted “in” would how vote “out”.

This switch in votes would see an overall result of 51.2% to 48.8% in favour of remaining in the EU.

However, the poll also shows there is no major appetite for a second referendum with 51.3% saying they don’t want a second poll.

Mrs May’s decision to put sovereignty and regaining our control of borders ahead of access to a single market is backed by most voters.

A majority (52.6% to 47.4%) say border control is more important than access to the single market.

But there is mounting concern about the prospect of a hard Brexit with 25.8% saying they were less positive about Britain’s future after hearing the Prime Minister set out her Brexit plans. By comparison 21.3% said they were more positive.

The poll, which included readers in Scotland, Wales and Northern Ireland, also shows that more than half of respondents (54.7%) expect the UK to break up within a decade as a result of Brexit.

Mrs May remains the most popular party leader. Nearly a third rated (30.8%) her performance as the most impressive performer since the EU referendum last year.

First Minister Nicola Sturgeon was next (19.2%), followed by Plaid Cymru’s Leanne Wood (16.7%), Scottish Tory leader Ruth Davidson (16.2%), former UKIP leader Nigel Farage (14.8%), Jeremy Corbyn (11.0%) and Lib Dem leader Tim Farron on (8.9%).

The survey, which included readers of Trinity Mirror regional titles as well as those of the Daily Mirror and Daily Record, showed that people in some of the areas which voted solidly to Leave were having a change of heart.

In Birkenhead 23.1% who voted out would now voted to remain, in Stockton-on-Tees 22.5% would switch to remain and in Camborne, Cornwall, 24.4%.

The places with the highest proportion of people who voted “in” but would switch to “out” are Hull (19.2%), Reading (15.9%) and Hamilton (15.0%).

Towns which most strongly backed Mrs May’s decision to make regaining control of our borders a priority were Grimsby (75.3%), Burton (69.8%), Middlesbrough (67.8%) and Hull (64.5%).

Those areas which put retaining access to the single market first were Cambridge (62.2%), Cardiff (56.9%), Bath (56.4%), Woking (54.7%), Reading (54.4%) and Manchester (53.7%).

Labour MP Pat McFadden, who backs the Open Britain campaign, said: “This poll shows the country continues to be divided over Brexit.

“The small but significant shift to Remain should be a warning to the Prime Minister that it would be a big mistake for her to believe the small majority for Leave in the referendum meant she didn’t have to care about the concerns of the 48% who voted Remain.

“She is driving the country towards a hard and potentially destructive Brexit when she should be trying to unite the country. We must ensure that jobs and prosperity are not sacrificed because of the ideological obsessions of hard-right Brexiteers.”

But Change Britain spokeswoman Chloe Westley said: “A number of recent polls show strong support for Brexit and that both Remain and Leave voters now want politicians to deliver the referendum result and to take back the control we need to build a better future for working class communities and for Britain.”
