Palantir lobbied a health minister to consider extending its artificial intelligence software into GP records, according to WhatsApp messages disclosed under freedom of information laws.

The messages, obtained by campaign group Foxglove and shared with the Guardian, show the US technology company arguing that its software should be used to join up GP records with hospital data. The Guardian reported the story on 9 November 2026.

GP data was expressly ruled out of Palantir's existing £330 million contract with NHS England to run its Federated Data Platform, known as the FDP. Ministers promised in 2023 that GP data would not be part of the national platform.

What the messages show

The exchanges appear to be between Palantir's UK boss, Louis Mosley, and the former health minister Zubir Ahmed. They span several months, from July 2025 to March 2026, with the push on GP records coming in February 2026.

Palantir told Ahmed that “the logic of joining up primary and secondary [care] data is unarguable” and described its Foundry software as “ideal” for the job. The company said applying the software to GP data could bring “faster access to GPs … more effective and targeted management of frail patients, and more effective preventative care”.

The executive's name was redacted in the documents released by the Department of Health and Social Care, but Palantir did not deny that it was Mosley.

The messages also show Palantir urging Ahmed to get ahead of likely political opposition from doctors and critics, including Green Party leader Zack Polanski and Your Party leaders Jeremy Corbyn and Zarah Sultana.

Doctors warn over patient trust

The British Medical Association and patient groups oppose bringing GP records into the platform, warning that it could undermine trust between patients and their doctors. Critics have also pointed to Palantir's work for the Israeli military and US Immigration and Customs Enforcement.

Palantir says its Federated Data Platform has already helped cut surgery waiting times and discharge delays in hospitals, and argues it would deliver more benefits with ministerial backing.

Foxglove, which obtained the messages, has separately questioned whether ministers are considering extending Palantir's NHS contract by two years. In a statement on 6 November, the group said the contract requires the company to provide bridging support for up to 24 months if the contract ends, so ending it would not require an immediate replacement.

Health Secretary Yvette Cooper has told Parliament that the government is still reviewing Palantir's NHS contract, which reaches its next end point in 2029. She has stressed the importance of sovereignty in NHS technology, but has not said publicly what decision ministers will take.

The disclosure adds to scrutiny of the relationship between Palantir and the government at a time when the future of the Federated Data Platform, one of the NHS's most sensitive data projects, remains undecided.
