UK Lawmakers Warn Palantir Dependence Is an "Unacceptable Weakness"

Today’s Focus

A cross-party group of British lawmakers has warned that the United Kingdom’s growing reliance on US data analytics firm Palantir Technologies poses an “unacceptable point of weakness” for national resilience, according to a report covered by WIRED, the Financial Times, Reuters and Bloomberg.

The All-Party Parliamentary Group (APPG) on Artificial Intelligence and the APPG on Defence published findings urging ministers to limit Palantir’s role in critical public data systems, citing concerns about overdependence on a single foreign supplier embedded across defence, policing and health.

The report focuses heavily on Palantir’s £330 million contract to build the National Health Service’s Federated Data Platform, awarded in 2023. Bloomberg reports that MPs want the government to review whether Palantir should hold a “significant role” in systems that aggregate patient records across NHS England.

Lawmakers cite three categories of risk. First, concentration risk if a single US vendor controls interoperability across departments. Second, geopolitical exposure given that Palantir is subject to US jurisdiction and export controls. Third, transparency gaps, with parliamentarians complaining about limited public disclosure of contract terms, according to the Financial Times.

Palantir, co-founded by Peter Thiel and led by chief executive Alex Karp, also holds contracts with the UK Ministry of Defence and counter-terrorism agencies. Reuters notes the company has expanded rapidly across Europe since 2022, often without competitive tender under emergency procurement rules used during the pandemic.

The Cabinet Office said in a statement quoted by Reuters that all contracts meet UK security standards and that data remains under British control. Palantir told WIRED its platforms are configured so that customers, not the company, own and govern the underlying data.

The Debate

Supporters argue

Defenders of the existing contracts, including UK Health Secretary Wes Streeting in remarks reported by the Financial Times, argue that Palantir’s Foundry software has measurably improved NHS efficiency, helping clear elective surgery backlogs and coordinate organ transplants.

Conservative MP Mark Francois, quoted by Bloomberg, said replacing Palantir’s defence integrations mid-deployment would create operational gaps that adversaries could exploit. He argued that the company’s tools are already battle-tested with US and Ukrainian forces.

Palantir executives, in a statement to WIRED, said the firm operates under strict UK data-protection law and that its architecture allows the government to extract its data and switch vendors. The company contends that “sovereignty” concerns conflate where a vendor is headquartered with where data physically resides.

The Tony Blair Institute, which has advocated for digital modernisation, has separately argued that bespoke domestic alternatives would take years and cost more, leaving public services dependent on legacy systems in the interim. Supporters frame the APPG report as legitimate scrutiny that should not derail contracts delivering current value.

Critics argue

Critics, led by Labour MP Chi Onwurah and Liberal Democrat science spokesperson Victoria Collins, contend that the scale of Palantir’s footprint has outpaced parliamentary oversight, according to the Financial Times.

Onwurah told WIRED that concentrating NHS, defence and policing data with one US vendor creates a “single point of failure” that could be exploited if relations with Washington deteriorate. She pointed to recent US tariff disputes as evidence that allied status does not guarantee continuity.

Civil-liberties group Foxglove, which has sued over the NHS contract, argues that Palantir’s procurement bypassed meaningful competition and that patient trust has not been adequately secured. Reuters reports the group is pursuing a judicial review.

Some critics also raise ideological concerns. The Guardian has reported on statements by Palantir co-founder Peter Thiel and chief executive Alex Karp expressing scepticism of European regulation, which opposition MPs argue is incompatible with stewardship of British public data. They want a mandated cap on any single vendor’s share of sensitive government contracts.

What the experts say

Independent analysts say the underlying issue is supplier concentration rather than Palantir specifically. The Ada Lovelace Institute, a nonpartisan research body, published analysis in 2024 finding that fewer than five firms dominate UK public-sector data infrastructure, with limited published risk assessments.

Gina Neff, executive director of the Minderoo Centre for Technology and Democracy at the University of Cambridge, told the Financial Times that the UK lacks a coherent framework for evaluating foreign tech dependencies, unlike the European Union’s Digital Operational Resilience Act.

The National Audit Office reported in 2024 that the NHS Federated Data Platform’s procurement met legal requirements but flagged weaknesses in measuring long-term value for money. The Institute for Government has noted that emergency procurement rules used during COVID-19 reduced competitive tendering across Whitehall, a pattern that persisted afterward.

Internationally, the Center for European Policy Analysis has documented similar debates in Germany and France, where Palantir contracts with police agencies prompted court challenges. Researchers cited by Reuters say no consensus has emerged on whether sovereign alternatives are technically feasible at comparable cost within five years.
