Shadow minister says if party’s demands are met she would not expect a second public vote

Labour is prepared to sign up to a Brexit deal with the government without the promise of a referendum attached if cross-party talks make significant progress in the coming days, one of the party’s negotiators has said.

With talks set to resume on Monday, Rebecca Long-Bailey, the shadow business secretary, made clear that if Labour’s Brexit demands were met, she would not expect the party to insist it be put to a public vote.

“Our party policy has always been that firstly we want to get a Brexit deal that puts our economy and living standards first and protects our environmental protections, workplace protections, health and safety standards,” she said.

“If we don’t get a deal that satisfies those objectives – if it’s a damaging deal, a damaging Tory Brexit deal, or there’s a risk of us moving towards a no deal – in that circumstance, we’ve said that all options should be on the table, and that includes campaigning for a public vote,” she added.

Her intervention came ahead of what is widely expected to be a combative meeting of Labour’s ruling national executive committee (NEC) on Tuesday, to sign off its manifesto for the European parliamentary elections.

Labour’s deputy leader Tom Watson, who sits on the NEC, made clear on Sunday that he will use the meeting to push for a confirmatory vote on any Brexit deal to be included in the manifesto – even urging Labour supporters on Twitter to lobby potential waverers.

Please let your reps on the NEC know if you want them to support a confirmatory ballot on a brexit deal in our euro manifesto: @hudaelmi_ @Yasmine_Dar @LabourRachel @NavPMishra @ClaudiaWebbe @darrenw_cardiff @jonlansman @AnnDHenderson @PeterWillsman

He received unlikely support from Jon Lansman, the founder of the Corbyn-backing campaign group Momentum, who replied: “At conference we agreed: ‘If the Govt is confident in negotiating a deal that working people, our economy & communities will benefit from they should not be afraid to put that deal to the public.’ So surely we too can all agree to a confirmatory vote on any govt deal in our manifesto!”

Meanwhile, 21 of the party’s candidates for the European elections, including 11 sitting MEPs, sought to increase the pressure on the NEC, by signing a pledge to say they will push for a referendum with remain on the ballot paper, and if a ballot is called, campaign for remain.

Andrew Lewin, of party campaign group Remain Labour, said he hoped more candidates would sign up in the coming days.

“Remain voters across the country who want to defeat Nigel Farage’s Brexit party can now vote with confidence and enthusiasm for Labour candidates who have pledged to fight for our future, as members of the European Union,” he said.

Many at Westminster believe the cross-party Brexit talks, convened by Theresa May after her deal was rejected three times and due to resume this week, are destined to fail.

Quick guide Labour's key moments in the Brexit process Show Hide August 2016 Making explicit the position he held since the Brexit vote, Jeremy Corbyn says Labour will respect the result of the referendum. "I think we've had a referendum, a decision has been made, you have to respect the decision people made." June 2017 Wary of upsetting voters in leave areas, Labour's manifesto for the 2017 general election declares: "Labour accepts the referendum result and a Labour government will put the national interest first." September 2018 Over five gruelling hours, Labour's internal contradictions over Brexit are distilled into a conference composite motion that makes the party's priority to seek a general election but, failing that, says a referendum should not be ruled out. February 2019 Chuka Umunna and remain MPs from both Labour and the Conservatives quit to form the Independent Group, citing Brexit as a major motivating factor. March 2019 Labour backs attempts by backbenchers to keep the option of a public vote on the table to stop a no-deal Brexit or May's deal. When all options considered by parliament fall, Labour enters into Brexit talks with the government but says May must move on a customs union if they are to succeed.

But Long-Bailey insisted negotiations had been productive and “gone into a lot of detail”, and hinted that the government was signalling a willingness to compromise on some issues, including workers’ rights.

“There has been movement in specific areas – we’ve had fantastic discussions on workers’ rights, for example, and the government seems quite amenable to moving towards what I’ve been asking for. We’re waiting at the moment to see if that turns into pens on paper,” she told Sky News’s Sophy Ridge.

The NEC will consider a draft manifesto, presented by Labour’s policy chief, Andrew Fisher, which is expected to stick closely to the conference policy of supporting a referendum only in specific circumstances.

However, shadow cabinet ministers keen for the party to back a people’s vote argue that Labour’s formal position changed when Corbyn whipped his MPs to support a confirmatory referendum earlier this month.

The shadow Brexit secretary, Keir Starmer, who attends the cross-party talks alongside Long-Bailey and John McDonnell, said in the House of Commons during the debate: “At this late stage it is clear that any Brexit deal agreed in this parliament will need further democratic approval.”

He was among those angered by the text of a campaign leaflet for the European elections leaked to the Huffington Post last week that failed to mention a referendum.

However, the Grimsby MP Melanie Onn, and the Stoke-on-Trent Central MP Gareth Snell, are among the backbenchers who believe any mention of a referendum will put their voters off – not least in this Thursday’s council elections. Their view is shared by several members of the shadow cabinet.
