Summary:

- Metropolitan Police have launched a criminal investigation into alleged unauthorised database access linked to the founding of Your Party.

- A man in his 20s was arrested on suspicion of an offence under the Computer Misuse Act 1990.

- The suspect was released pending further enquiries without charge, while a woman was also interviewed by police.

- Neither Jeremy Corbyn nor Zarah Sultana, who co-lead Your Party, has been accused of wrongdoing.

- Police have not publicly identified the political party involved, although sources linked the investigation to Your Party's founding dispute.

- Your Party was established in 2025 by former Labour leader Jeremy Corbyn and MP Zarah Sultana.

- The party experienced internal disagreements after approximately 800,000 people received an email inviting them to purchase memberships.

- Sultana supported the membership launch, while Corbyn publicly described it as unauthorised and urged supporters to disregard the email.

- Membership subscriptions were advertised at £5 monthly or £55 annually, with discounted rates available.

- A Your Party spokesperson said its systems were secure, described the incident as isolated and declined further comment.

Why this matters: The investigation raises questions about data security and internal governance during Your Party's formation. It also highlights tensions between the party's leadership over its membership launch, although no charges have been brought.

What’s next: Metropolitan Police will continue investigating the alleged unauthorised database access. Further developments will depend on whether investigators identify sufficient evidence to bring charges, while Your Party maintains that its systems are secure.
