Whistleblowing website Wikileaks is offering a £20,000 ($25,900) reward for information on how Labour Party officials "have attempted to stop Jeremy Corbyn becoming and staying on as leader".
The group said it wants to help members "understand how their top party officials are attempting to undermine their democratic will".
The secretive organisation led by Julian Assange, said it is hoping to emulate what they achieved in the US, when they released thousands of emails and attachments from the Democratic Party's National Committee (DNC).
They revealed that officials allegedly plotted against Hillary Clinton's rival Bernie Sanders when he ran against Clinton in the hard-fought primary contest.
Their release prompted the resignation of a number of high-profile officials from the DNC, including its chair Debbie Wasserman Schultz, who quit before the party's convention and chief executive Amy Dacey.
Party chiefs later issued an apology to Sanders for "inexcusable" emails which tried to undermine his White House campaign.
But he refused to let the email scandal eclipse his campaign and he told the convention that Clinton "must become the next president of the United States".
Now Wikileaks "is now moving on to the machinations of top officials in the UK Labour Party to tilt the scales against the membership-elected leader Jeremy Corbyn in favour of his challengers" the group said in a statement, released on 23 September – the day before Corbyn defeated challenger Owen Smith with 61.8% of the vote.
"Like officials at the top of the Democratic Party, those in the Labour Party apparatus are meant to be neutral in the process of electing leadership candidates. But it is clear this has not been the case," Wikileaks said. "The scales are being tilted."
"Wikileaks is offering a £20,000 reward for information which will help Labour Party members understand how their top party officials are attempting to undermine their democratic will," they added.
"We are particularly interested in #LabourLeaks information about strategising at the highest levels of the Labour Party and its National Executive Committee."
A Labour Party spokesman declined to comment to the IB Times UK.
