MPs Warn Palantir’s Access to NHS Patient Data Poses Serious Privacy Risks

Controversy Erupts Over NHS England Granting Palantir Access to Identifiable Patient Records

MPs have raised alarms over NHS England‘s recent decision to grant the US tech giant Palantir access to identifiable patient data, branding the move “dangerous” and warning it could erode public trust in data privacy. The health service has permitted Palantir and other contractors to handle patient information before it undergoes pseudonymisation, stirring fears about the security and confidentiality of sensitive medical records.

Inside NHS England’s Data Access Decision

According to an internal NHS briefing leaked to the Financial Times, this new arrangement affords “unlimited access to non-NHSE staff” to segments of the NHS’s federated data platform (FDP), which contains identifiable patient details. This platform, developed through a £330 million contract awarded to Palantir, aims to integrate fragmented health datasets using AI technology to enhance treatment efficiency and NHS performance.

Despite the ambitious goals, the contract has drawn fierce criticism from campaigners and MPs wary of the risks posed to patient privacy. The briefing explicitly acknowledges “considerable public interest and concern” surrounding Palantir’s level of access to patient data.

Palantir’s Controversial Background Amplifies Concerns

Palantir’s involvement raises eyebrows given its role in controversial US government operations, including support for Donald Trump’s ICE immigration enforcement and military contracts across several nations. Critics argue that such a company’s deepening involvement in the NHS jeopardizes the confidentiality and ethical use of patient information.

Patient Groups Demand Transparency and Consent

The Patients Association expressed serious concern over the lack of patient consultation regarding this significant expansion of data access. CEO Rachel Power emphasized that patients demand “transparency, clear boundaries around access to their data, and to be consulted when changes to those agreements are proposed.”

MPs Demand Halt to Palantir’s Expanding Role

Rachael Maskell, Labour MP and former NHS worker, has publicly called for an immediate halt to the project. She warned, “As Palantir get their claws deeper into our NHS data, it opens the door to greater private interests. This is a dangerous development. The government must get a grip on this project before it is too late.”

Official NHS Response and Security Measures

NHS England insists that only a limited number of individuals working on the FDP platform receive access, all of whom must hold government security clearance. The organisation maintains “strict policies in place for managing access to patient data” and conducts regular audits to ensure compliance. External contractors are closely monitored, with any instances of access to identifiable data during system pipeline work recorded and controlled.

Palantir stresses it acts solely as a “data processor,” not a “data controller,” meaning its software operates strictly under NHS directives. The company asserts that using data beyond these instructions would be illegal and technically blocked by granular access controls overseen by NHS authorities.

Growing Public Distrust and Political Scrutiny

Public skepticism towards Palantir’s expanding footprint in the UK public sector is mounting. Recent polling reveals that over two-thirds of UK citizens worry about the company’s increasing number of government contracts, with 40% explicitly distrusting Palantir to handle NHS patient data responsibly.

Martin Wrigley, a Liberal Democrat on the Commons technology select committee, criticized NHS England’s approach, stating, “This somewhat cavalier attitude to data security shows the project lacks security by design. The public has every right to be concerned that data privacy is not the top priority.”

Campaign Groups Demand Removal of Palantir from NHS

Tom Hegarty, communications head at the tech equity campaign group Foxglove, condemned Palantir’s involvement: “NHS patients never consented to have their data accessed by a company whose record is in targeting people rather than caring for them. Palantir fails the trust test. The government should cut Palantir out of our NHS once and for all.”

Palantir’s Expanding Role in UK Public Services

Beyond healthcare, Palantir is poised to deepen its presence in UK law enforcement. The Guardian recently revealed the company is close to securing a deal with the Metropolitan Police to deploy AI tools for intelligence analysis in criminal investigations. This expansion faces widespread opposition from citizens and several backbench MPs.

Conclusion: NHS Under Pressure to Balance Innovation with Privacy

The NHS’s push to leverage AI and big data to improve healthcare outcomes stands at a crossroads. While technological innovation promises efficiency and better patient care, the deepening access granted to Palantir raises profound questions about data privacy, transparency, and public trust. The government faces mounting pressure to tighten controls and ensure patient confidentiality remains sacrosanct in the digital age.
