A total of 151 Brexit-related motions have been submitted by local Labour parties, with dozens asking the party’s annual conference to back either a general election or a fresh public vote on the final Brexit deal.

It comes after one of Labour’s most powerful figures, Sadiq Khan, the mayor of London, called for another vote on Brexit, insisting there are now just two possible outcomes for the UK in the negotiations – either a bad deal, or a no-deal.

It is likely to pile pressure on Jeremy Corbyn, who has refused to rule out the idea, but has consistently said that it is not Labour policy to support a fresh referendum.

The document of 272 motions, seen by The Independent, shows that 55 per cent of them relate to Labour’s position on Brexit, with other issues including the party’s stance on antisemitism, welfare, government contracts and schools.

On Monday, the party’s conference arrangement committee will sift through the raw motions and decide which ones to put forward to Labour’s conference in Liverpool next week.

Each Constituency Labour Party (CLP) has the opportunity to propose a “contemporary motion” for discussion at conference and campaigners for a new public vote claim the number of motions supporting the idea will dominate.

One motion from Camberwell and Peckham, the constituency of the party’s former deputy leader, Harriet Harman, notes the “Chequers deal is dead” and calls for a meaningful vote in Parliament, a UK-wide referendum on the final terms of Brexit or a general election.

A substantial amount of the motions, however, are based on the left-wing statement backed by Another Europe is Possible and Labour for a People’s Vote.

As well as calling for a fresh vote, it also says Labour should “form a radical government – taxing the rich to fund better public services, expanding common ownership, abolishing anti-union laws and engaging in massive public investment”.

One of the national organisers at Another Europe is Possible, Michael Chessum, said: “If we don’t have a manifesto commitment for a fresh referendum, we will end up going into an autumn election either promising a ‘bespoke Labour Brexit’ which we have no time to negotiate, or offering a Norway-style deal which is straightforwardly worse than EU membership and will leave Corbyn with no seat at the European table.

“Of the options, soft Brexit is the least popular with the electorate,” he added.

Davis resignation letter said: “As you know there have been a significant number of occasions in the last year or so on which I have disagreed with the Number 10 policy line, ranging from accepting the [European] Commission’s sequencing of negotiations, through to the language on Northern Ireland in the December Joint Report. “At each stage I have accepted collective responsibility because it is part of my task to find workable compromises, and because I considered it was still possible to deliver on the mandate of the referendum, and on our manifesto commitment to leave the Customs Union and the Single Market. “I am afraid that I think the current trend of policy and tactics is making that look less and less likely.” He went on to argue that the “general direction” of Ms May’s policies would leave the UK “in at best a weak negotiating position, and possibly an inescapable one”. AFP/Getty Brexit casualties Steve Baker - Resigned from Minister at the Department for Exiting the European Union role July 2018 - Mr Baker, a key Tory figure in the Leave campaign, was David Davis’s main lieutenant at Dexeu, and was hailed as ”courageous and principled” by other Brexiteer Tories as he also left.

In his resignation letter to the prime minister, Mr Johnson said: "On Friday, I acknowledged that my side of the argument were too few to prevail and congratulated you on at least reaching a Cabinet decision on the way forward. "As I said then, the government now has a song to sing. "The trouble is that I have practised the words over the weekend and find that they stick in the throat." Reuters Brexit casualties Conor Burns - Resigned from Parliamentary Private Secretary to Foreign Secretary role July 2018 - A Brexit supporter who worked alongside Boris Johnson stated in his resignation letter: “I've decided it's time to have greater freedom. I want to see the referendum result respected. And there are other areas of policy I want to speak more openly on.” Rex Brexit casualties Chris Green - Resigned from Department for Transport role July 2018 - The Bolton West MP said: "Parliament overwhelmingly decided to give the decision of whether to leave or remain in the European Union to the British people and they made an unambiguous decision that we ought to leave. "I have always understood the idea in 'Brexit means Brexit' is that the final deal should be clear to me and my constituents - that we have, in no uncertain terms, left the European Union. Twitter Ads info and privacy "The direction the negotiations had been taking have suggested that we would not really leave the EU and the conclusion and statements following the Chequers summit confirmed my fears. "I recognise that delivering Brexit is challenging, however I had hoped at tonight's meeting that there would be some certainty that my fears were unfounded but, instead, they have been confirmed. "I have been grateful for the opportunity to serve as Parliamentary Private Secretary and it is with regret that I offer my resignation with immediate effect." PA Brexit casualties Maria Caulfield - Resigned from Conservative Party vice-chair for women role July 2018 - resigned over May's Chequers plan. Lewes MP warned that the direction of travel did “not fully embrace the opportunities that Brexit can provide”. Ms Caulfield said in her letter to the PM: “The policy may assuage vested interests, but the voters will find out and their representatives will be found out. This policy will be bad for our country and bad for the party. “The direct consequences of that will be prime minister Corbyn.” PA Brexit casualties Ben Bradley - Resigned from Conservative Party vice-chair for young people role July 2018 - resigned over May's Chequers plan. The Mansfield MP said: “I admit that I voted to Remain in that ballot. What has swayed me over the last two years to fully back the Brexit vision is the immense opportunities that are available from global trade, and for the ability for Britain to be an outward looking nation in control of our own destiny once again. “I fear that this agreement at Chequers damages those opportunities; that being tied to EU regulations, and the EU tying our hands when seeking to make new trade agreements, will be the worst of all worlds if we do not deliver Brexit in spirit as well as in name, then we are handing Jeremy Corbyn the keys to No10.” PA Brexit casualties Robert Courts - Resigned from Parliamentary Private Secretary role July 2018 - resigned over May's Chequers plan. MP Mr Courts said: “I have taken a very difficult decision to resign my position as [parliamentary private secretary] to express discontent with the Chequers [plans] in votes tomorrow. “I had to think who I wanted to see in the mirror for the rest of my life. I cannot tell the people of Woxon that I support the proposals in their current form.” Getty Brexit casualties Scott Mann - Resigned from Parliamentary Private Secretary role July 2018 - resigned over May's Chequers plan. "I fear elements of the Brexit white paper will inevitably put me in direct conflict with the views expressed by a large section of my constituents. I am not prepared to compromise their wishes to deliver a watered-down Brexit. "The residents of North Cornwall made it very clear that they wish to have control over our fishery, our agricultural policy, our money, our laws and our borders. I will evaluate those principles against the Brexit white paper and ensure that I vote in line with their wishes." Rex

Activist Alena Ivanova, who started an anti-Brexit petition of Momentum members that attracted 6,000 signatures, added there has been a “false idea” of division between those advocating a new referendum and those who want a general election.

She said: “That’s completely wrong, because the push for a referendum is clearly being led by left-wing activists, who want to see Corbyn walk into No 10 and have fought for it. We all want a general election, but the issue is what will go in our manifesto about Brexit?”

But on Sunday, shadow international trade secretary Barry Gardiner reiterated his opposition to the idea, suggesting it would hand Theresa May a “lifeline”.

He said the first referendum had caused “real divisions” in the country, adding: “I think the challenge now is to try to heal society.
