A journalist working for Iran’s state-sponsored broadcaster has been suspended from the Labour Party after he allegedly used his membership to infiltrate and film a vote of no confidence against a pro-Israel MP, The Daily Telegraph has been told.

Robert Carter, who joined Labour during the 2015 leadership hustings, is now being investigated by Labour’s compliance unit after footage of a constituency party meeting was broadcast by Press TV.

It comes days after this newspaper revealed that Mr Carter had been accused of filming a meeting of Joan Ryan MP’s Enfield North constituency party last Thursday, despite journalists and film crews being banned from the event.

The vote was called amid a string of similar motions against other moderate MPs who have been openly critical of Jeremy Corbyn’s leadership, which critics in Labour have branded a “purge”.

The footage was later published by Press TV, which was stripped of its UK broadcasting licence by Ofcom in 2012, prompting an outcry from Labour MPs and Tom Watson, the party’s deputy leader, who warned the controversy made a “farce of the proceedings”.
