Jeremy Corbyn and Zarah Sultana are preparing to reopen membership registration for their new political party (Your Party) this week, despite failing to agree on a joint statement.
The move follows weeks of tension after Sultana unilaterally launched an online portal that drew 20,000 sign-ups but was denounced by Corbyn and other Independent Alliance MPs as unauthorised.
She later backed down, cancelling legal threats and admitting the row had demoralised supporters.
Although relations between the pair remain cordial, sources reveals Corbyn feels a complete lack of trust after repeated unilateral actions.
Allies of Sultana accused party insiders of excluding her and running a sexist boys’ club, while her critics dismissed the claims as unfounded.
The Independent Alliance, which includes MPs Shockat Adam, Ayoub Khan, Adnan Hussain and Iqbal Mohamed, is still backing Corbyn.
Meanwhile the dispute has strained relations across the group, with MPs reporting online abuse linked to the controversy.
Despite divisions, both sides insist the founding conference will proceed on schedule, where members will decide the party’s constitution, leadership and policies by one-member-one-vote.
Supporters hope the fresh membership launch will help move beyond the chaotic start.
