Health service staff have raised alarms over engineers from Palantir Technologies being granted NHS email accounts, which provide access to a directory containing contact details of 1.5 million NHS employees. Palantir, awarded a £300 million contract in 2023 to implement its Federated Data Platform (FDP) for NHS England, has also gained access to NHS SharePoint and Microsoft Teams. While NHS England asserts that the FDP will enhance patient record management and treatment personalization, many staff members are uneasy about Palantir’s controversial background in AI surveillance and its founders' statements against the NHS. Concerns have been voiced about the ethical implications of allowing a company associated with military technology to operate within the public health sector. NHS staff have reported participating in meetings with Palantir employees without prior knowledge of their affiliations. Critics, including healthcare advocates, are calling for a comprehensive review of private contractors within the NHS to ensure alignment with its foundational values. An NHS spokesperson emphasized that all data access remains under NHS control and is governed by strict confidentiality agreements.
