A nationwide survey of 9,500 people conducted by campaign group Right to Vote found 58.1 per cent who expressed a view, now want another public vote on the UK’s withdrawal from the European Union.

Polling found high levels of support for the idea in London, including in Mr Corbyn’s Islington North seat, where 75 per cent of those polled backed a Final Say.

In Theresa May’s Maidenhead constituency, 59 per cent of voters also supported the idea.

The same percentage of voters in leading Brexiteer Boris Johnson’s Uxbridge and Ruislip South constituency were also behind the idea of a public vote.

Conservative MP Dr Phillip Lee, chair of Right to Vote, revealed the findings at Prime Minister’s Questions on Wednesday – a day after Ms May announced she would be seeking another extension to Article 50.

The group was formed by several MPs in January in response to what it describes as the “government’s failure to navigate Brexit”.

Members include former Tory ministers Dominic Grieve, Justine Greening and Sam Gyimah, as well as Independent Group MPs Heidi Allen, Anna Soubry and Dr Sarah Wollaston, who quit the party in February.

“Asking for more time and opposition help to salvage a deal nobody wants is yet again merely delaying the moment of truth,” Mr Grieve said. “We need a meaningful delay to agree a practical and credible proposal which can be put to the people for a final say. What started with the people should end with the people.”

The new polling data comes as senior figures within Labour demand Mr Corbyn seeks to secure a second referendum as part of any cross-party Brexit deal struck with Ms May.

A string of Labour MPs, including frontbenchers such as shadow foreign secretary Emily Thornberry, have written an open letter to Mr Corbyn in The Independent, insisting it would be “untenable for Labour not to insist” on taking the decision back to the public.

Mr Corbyn is holding talks with the prime minister in a bid to break the impasse in parliament and find a Brexit deal that can win enough support to get through the Commons.

“The views of members are clear. Labour’s democratically established policy, passed at party conference in September 2018, is to oppose a Brexit deal which does not meet Labour’s six tests and put any deal that does to a public vote,” the group of Labour MPs wrote in their open letter. “It would be untenable for Labour not to insist on a public vote on a deal which did not meet these tests.”

“We – your supporters – urge you to make a confirmatory public vote your bottom line in negotiations with Theresa May and to fight to bring this government down.”
