Green Party MPs have called on the government to scrap its NHS contract with US tech giant Palantir and investigate how the deal was awarded.
In a letter dated 10 February 2026 addressed to the Cabinet Secretary, Green MPs pressed for ‘an immediate inquiry’ into the government’s NHS and Ministry of Defence (MoD) contracts with the tech firm, raising concerns that Palantir is becoming ‘deeply embedded’ in both organisations.
They said: ‘The UK’s reliance on Palantir risks making it even more difficult for the UK to confront or even publicly disagree with the US administration’ and urged dependence to be reviewed in order to ‘secure the UK’s digital sovereignty.’
The letter also urged officials to assess any potential influence on the contracts from former UK Ambassador to the US, Peter Mandelson. It highlighted reports that Global Counsel, the lobbying firm that Mr Mandelson co-founded, had links to Palantir.
Green Party MP, Sian Berry, said: ‘The Prime Minister has questions to answer.’
The move follows a separate letter sent last week by Green Party leader Zack Polanski to Health Secretary Wes Streeting in which he said: ‘Palantir has absolutely no place in the NHS’.
In November 2023, Palantir was awarded a seven-year contract worth £330m to deliver NHS England’s ‘federated data platform’ (FDP) – an NHS-controlled platform designed to connect vital health information across the service.
In March 2025, data chiefs raised concerns that the FDP would not be able to meet the ‘bespoke’ requirements of local systems across the NHS.
And, at the British Medical Association (BMA)’s annual representative meeting in June 2025, a motion was passed which described Palantir as ‘an unacceptable choice of partner’ to create an FDP for the NHS and urged that ties be cut.
Last July, Palantir’s UK head accused the BMA of putting ‘ideology over patient interest’.
In response, a government spokesperson said: ‘Ministers engage with a range of companies as part of their international travel and Palantir is a longstanding investor in the UK.
‘We utilise a range of international suppliers based on operational requirements, value for money, and compliance with our security and legal obligations, with all suppliers subject to rigorous due diligence.’
