The UK government has six months to decide whether to trigger a break clause in its $400 million contract with American software firm Palantir. As the National Health Service (NHS) rolls out the Federated Data Platform (FDP) to organize the nation's health data, the region of Greater Manchester is standing firm in its refusal to adopt the system, fueling a national debate over technology sovereignty and public trust.

The Manchester Rebellion

The Greater Manchester Integrated Care Board (ICB) has opted to stick with its homegrown Analytics and Data Science Platform (ADSP), developed over nearly a decade. Matt Hennessey, the region's chief data and analytics officer, told WIRED that the local platform is functionally superior and more trusted by the 3 million residents it serves. "If we were to fully adopt the FDP … it would be a retrograde step," Hennessey argued, noting that the ADSP is years ahead in certain functionalities.

The ADSP integrates primary care data that is currently unavailable on Palantir’s platform. Because it was built in-house, Manchester officials claim it offers greater flexibility, allowing them to swap out components if better technology emerges.

A Flashpoint for Controversy

The deal with Palantir has become a political lightning rod. Critics point to the company’s military contracts and its role in US immigration enforcement as evidence of a values mismatch. In June, a bipartisan group of UK politicians warned that relying on a single foreign vendor creates an "unacceptable point of weakness." Public sentiment has also been soured by past comments from Palantir co-founder Peter Thiel, who suggested the NHS should be "ripped from the ground."

The Case for the FDP

Despite the pushback, Palantir and the Department of Health and Social Care insist the FDP is delivering results. Data shows that 139 of roughly 200 NHS trusts are already "live" with the technology, which is credited with cutting hospital stays and maximizing operating theater efficiency. Proponents like independent consultant Tom Bartlett argue that there is no viable alternative to Palantir's "lift and shift" capability, warning that terminating the contract would force many hospitals back to using paper and spreadsheets.
