Concerns about Palantir’s work with UK police are growing, Liberty Investigates recently revealed how Palantir has established a “real-time data-sharing network” with some forces that includes sensitive personal details of vulnerable victims, children and witnesses alongside suspects.

Details of such systems are routinely kept from public view. In both 2024 and 2025, multiple FOI requests about Palantir’s police contracts —including from Liberty and the Good Law Project—were referred to the CRU, which advised forces to withhold information.
