A regional publisher has revealed one in seven Leave voters now backs Remain after polling readers of its regional titles in what it claims is the “largest sample” of opinion on Brexit.

Trinity Mirror has published the data collected from surveys undertaken on its regional news websites, which found overall that one in 10 voters would now consider voting differently from the way they did in the 23 June referendum.

The polling was held across 82 sites at the time of Prime Minister Theresa May’s speech setting out the nation’s plan for negotiating leaving the European Union, with TM’s central data unit in Manchester collating approximately 46,500 responses since.

Overall, the survey showed that finds that if the EU referendum were held again the result would be reversed, with 51pc voting for Remain and 49pc for Leave.

The TM survey found that 13.5pc of those who voted Leave would now vote in, compared to 9.3pc of Remain voters who would now back Leave.

As well as carrying the results in yesterday’s Daily Mirror, several of TM’s regional titles posted the results in their websites on Sunday night and in yesterday’s print editions, such as North East daily The Journal, below.

The poll was conducted using Google Surveys which appeared randomly and only once to each unique user, meaning people could not vote multiple times.

Responses to six questions on the topic of Brexit which were answered too quickly were filtered out, while polling was not conducted on the traditionally left-leaning Mirror’s site to ensure a representative sample.

Of the individual local results David Higgerson, digital publishing director for Trinity Mirror, told HTFP: “Our newsrooms probably aren’t surprised by the results as that’s what we’re hearing and seeing in a lot of places, but it’s quite exciting to have probably the largest sample of Brexit sentiment since the 23 June vote at our disposal.”

“It’s a very strong tool to be able to look to readers and say ‘we think this is important, what do you think?’ As journalism evolves digitally it’s essential the audience is a part of that.”

Areas which voted Leave which would now vote to Remain include Stockton-on-Tees and Camborne, in Cornwall, while Hull, Reading and Hamilton, which all voted Remain, would now vote to Leave.

TM now plans to run other surveys on national issues in the same way, including further ones related to Brexit as negotiations begin.
