Trade unionists are much more likely to support Labour if the party offers them the chance of a People’s Vote, according to a new poll.

A survey of almost 2000 union members found that they would vote overwhelmingly to stay in the European Union if given the chance - prompting fresh demands for the party to move to reflect the views of the Labour movement as a whole.

The YouGov poll comes as Jeremy Corbyn is scheduled to meet trade union general secretaries this week to discuss Labour’s policy on Brexit.

It shows that more than two-thirds (71%) of rank-and-file trade union members would back a People’s Vote and choose to stay in the EU if a new referendum took place.

The vast majority also think Labour’s current position on Brexit is confusing or unclear.

Jo Stevens, the Secretary of the Trade Union Group of Labour MPs and a leading supporter of the People’s Vote campaign, said: “Labour’s official position is still too far behind that of our party members and voters, not to mention grassroots trade unionists who are the bedrock of our movement

“When Jeremy Corbyn meets with trade union general secretaries, I hope he hears the strong message from working people, trade union members up and down the country, that we want a People’s Vote just like his constituents do in Islington – because now, more than ever, we need those voices to be heard.”

The survey found that trade unionists are three times more likely to vote Labour if it backs a People’s Vote.

On Sunday, Labour’s shadow secretary of state for communities and local government, Andrew Gwynne, said that the party is now in favour of another referendum under all circumstances.

Speaking to Sky News, he said: “We are not going to get Labour’s Brexit deal presented by prime minister Johnson or prime minister Hunt, and so the realisation is that whatever they come back to Parliament with between now and October, we have to go back to the people and we have to say ‘is this really the Brexit that you want?’”

However, Labour MP Caroline Flint told The Andrew Marr Show that if it came down to a choice between a no-deal Brexit or no Brexit: “I won’t be voting to revoke Article 50.” Pressed on whether that meant she would back a no-deal Brexit, she said: “If that is where we end up, that is where I will be.”
