Tens of thousands of people have formally demanded that NHS England prevents the Palantir-powered national medical data platform from handling their personal information. More than 44,000 individuals have filed legal objections to their health data being shared with, stored in, or used by the nationwide Federated Data Platform (FDP), which uses AI technology from the US company Palantir.
This coordinated campaign leverages rights under data protection laws, meaning the NHS must cease using the data unless it can provide a "compelling reason" to continue. The objectors have also requested that the NHS halts processing their data through the Palantir platform while their primary request is being assessed.
Campaigners have expressed anger regarding Palantir's work for the Israeli military and Donald Trump's immigration crackdown. Two House of Commons select committees have called for Labour to exercise a break clause in the seven-year deal, which becomes active in February 2027.
Palantir states that the FDP, designed to connect health service data, helps reduce waiting lists and free up beds. A company spokesperson said Palantir software is assisting in delivering better care, citing 117,000 additional operations, a 14.3% reduction in discharge delays for long-stay patients, and a 5.6% improvement in cancer diagnosis within 28 days.
NHS England has stated that all NHS organisations maintain control of their data within the FDP, with suppliers unable to access it for their own purposes. NHS England will respond to the objection requests in accordance with data protection law.
