More than 44,000 people in Britain have formally objected to the use of their NHS health data in a Palantir-built system, citing the US tech company’s work with the Israeli military amid its genocide in the Gaza Strip.

The campaign targets the NHS Federated Data Platform, a £330 million system designed to connect health-service data, and calls for Palantir to be removed from the project over its role in Israel’s military attacks and the destruction of Gaza's healthcare system.
