Police investigate database dispute at Your Party founding

Summarised from 2 outlets · Updated 16 Oct, 13:33 · Archive

Police are investigating alleged unauthorised access to a political party's database linked to a dispute at the founding of Your Party, the left-wing political party established last year. The Metropolitan Police launched the investigation following a report in September 2025. Officers arrested a man in his 20s on suspicion of an offence under the 1990 Computer Misuse Act and released him pending further enquiries. A woman in her 30s was also interviewed under caution. Neither has been charged.

The investigation relates to a clash between the party's co-founders, former Labour Leader Jeremy Corbyn and former Labour MP Zarah Sultana, over a September 2025 email sent to around 800,000 people on the party's mailing list encouraging them to sign up as paying members. Sultana had promoted the membership portal while Corbyn described its launch as 'unauthorised'. Sultana later said her aim had been to 'safeguard the grassroots involvement that is essential to building this party'.

Neither the arrested man nor the interviewed woman are MPs, and neither Corbyn nor Sultana are accused of wrongdoing. The investigation continues.
