On April 21, 2026, Palantir Technologies faced a coordinated backlash from British lawmakers following the publication of a 22-point manifesto on the social media platform X. The document, which detailed the company’s ideological stance on Western defense, data governance, and the role of private technology in public infrastructure, prompted members of Parliament from across the political spectrum to demand a formal review of the company’s existing and future contracts with the United Kingdom government.
Central to the controversy is Palantir’s role in the National Health Service (NHS) Federated Data Platform (FDP). In late 2023, the company was awarded a contract worth approximately £330 million to manage the integration of patient data across the health service. Critics in the House of Commons, including representatives from the Labour, Liberal Democrat, and Conservative parties, argued that the sentiments expressed in the manifesto are incompatible with the public service values required for handling sensitive national health data.
Several MPs issued formal statements calling for the Cabinet Office and the Department of Health and Social Care to suspend further implementation of the FDP until a full audit of Palantir’s compliance with UK data sovereignty laws is completed. One senior MP described the manifesto as a politicized overreach that raises questions about the company’s neutrality as a service provider. The manifesto reportedly included assertions about the necessity of private sector dominance in national security and criticized traditional regulatory frameworks as impediments to technological progress.
Palantir, led by Chief Executive Officer Alex Karp and co-founded by Chairman Peter Thiel, has long been a major contractor for the UK Ministry of Defence and the Home Office. The company’s software, including the Foundry and Gotham platforms, is deeply embedded in British security operations. However, the April 21 manifesto has intensified existing scrutiny regarding the concentration of government data within a single foreign-owned entity.
As of the afternoon of April 21, a spokesperson for the UK government stated that all procurement processes follow strict transparency and security guidelines but did not rule out a review of the specific terms of the NHS agreement. Palantir has not officially retracted the post, though representatives for the Denver-based firm emphasized that the manifesto was intended to spark a dialogue on the future of Western technological resilience rather than influence specific contract negotiations. The total value of Palantir’s active UK government contracts is estimated to exceed £600 million across various departments.
