Three Your Party advisers have resigned from their roles and issued a parting swipe to “hostile” MPs.

Andrew Feinstein, Beth Winter and Jamie Driscoll, set up MOU Operations Ltd in April to support and advise Jeremy Corbyn and Zarah Sultana’s left-wing party.

Your Party was established in July this year after Mrs Sultana’s Labour whip was withdrawn the year prior.

Last month, the party threatened to collapse after a row between Mr Corbyn and Mrs Sultana over a paid membership portal she released without permission.

Mr Corbyn made a new membership portal six days later.

Donations made to Mrs Sultana’s first membership portal now sit in a bank account run by MOU amid threats of legal action.

Mr Feinstein, Mr Winter and Mr Driscoll, announced their resignations from MOU late on Wednesday, saying Mrs Sultana will now become the sole director of the company.

The trio said in a statement: “We have not been involved in any of the founding processes in any way.

“The role of holding donations was thrust upon us.

“The company we are responsible for has repeatedly been used without our agreement.”

The trio added: “From the day of the launch, we have raised concerns about the lack of agreement and appropriate governance.

“We asked the Your Party leadership to meet with us to resolve it… Only one of their directors agreed.”

Addressing the membership portal controversy, they said: “At the confusing launch of two membership systems, on Sep 18 and Sep 24, neither of which we had any part in, we faced the added complication of MOU holding data and membership records.”

They said that they had asked Your Party to take control of the organisation directly to allow the transfer of money and members, but five out of the six MPs declined.

The group said they tried multiple times to hand over control to Your Party and suggested key people in the left-wing group did not understand data protection laws.

Their statement concluded: “We have been extraordinarily patient, and tried to resolve this quietly behind the scenes.

“Your Party have claimed in emails and social media statements that we delayed the data transfer.

“We repeatedly asked them to stop making factually incorrect claims of this nature. They gave hostile briefings to journalists.

“We behaved with integrity.”

The Your Party membership issue still plagues the party, with more than 20,000 having signed up using Mrs Sultana’s membership portal.

This left MOU to handle a reported £800,000 in donations.

The issue of the membership portal is displayed throughout their Frequently Asked Questions page, with questions including “I signed up under Zarah’s portal on the 18th September only, am I a member?” and “how do I get a refund of membership fees paid to the first portal?”

Supporters of the party have received an email this week asking those who signed up using Mrs Sultana’s membership portal to sign up again and select “I already paid” as an option to receive free membership for three months.

Your Party is set to have their founding conference in Liverpool next month.

A Your Party source told The Telegraph on Thursday: “We view the statement as misleading in numerous ways but everyone wants to move on.

“We’ll be able to do so as soon as Zarah transfers the money to Your Party’s bank account, as she has promised, then we can focus on the founding conference.”
