Met Police Probe Your Party Founding Row: Key Details 2026

The Met Police investigation into the founding of Your Party has escalated into a criminal probe, focusing on an alleged unauthorised access of the party's database. This development has intensified the internal conflict within the leftwing party, which was established in summer 2025 by former Labour leader Jeremy Corbyn and former Labour MP Zarah Sultana.

Background of the Your Party Founding Row

Your Party was launched in July 2025 with high hopes of uniting leftwing voters. However, tensions quickly emerged between factions led by Corbyn and Sultana. In September 2025, Sultana promoted a new membership portal on X, urging members to pay £55 for membership. Corbyn condemned the site as a "false membership system" and advised supporters to ignore funding requests. Sultana defended her actions, stating her goal was to "safeguard the grassroots involvement that is essential to building this party," but later accused the party of being controlled by a "sexist boys' club."
