Louis Mosley, the UK and Europe boss of Palantir, has become a central figure in the debate over the company's growing influence in Britain's public sector. With over £600 million in deals with the NHS, Ministry of Defence, and police, Palantir is no ordinary contractor. However, its leadership's rightwing rhetoric and work for the US and Israeli militaries have drawn sharp criticism.
Who Is Louis Mosley?
Mosley, educated at Westminster School and Oxford University, previously worked in Tory politics as an assistant to Rory Stewart and as a councillor in Kensington and Chelsea. He joined Palantir in 2016 and now leads its 700-strong UK and Europe operation from a Soho headquarters. Despite not being a technologist, he has successfully pitched Palantir's AI tools to government ministers, securing contracts for Brexit planning, prisoner data management, and the NHS federated data platform.
Controversial Views and Associations
In a 2025 speech at an Alliance for Responsible Citizenship rally, Mosley heralded a revolution against the "distributed idea suppression complex," echoing themes from populist movements. His grandfather, Sir Oswald Mosley, was a fascist leader in the 1930s, a burden that cost him a Conservative parliamentary candidacy in 2017. Critics, including Green party leader Zack Polanski, have noted his preference for dark clothing, reminiscent of the "blackshirt" uniform.
Palantir's Role in UK Public Sector
Palantir's Foundry system, central to the NHS's federated data platform, has been praised for accelerating data analysis but criticized over privacy and security concerns. The company's reputation suffered due to its client ICE's actions and its technology's use in Gaza and Iran. Cross-party MPs have called for the NHS contract to be cancelled, citing fears over patient data security.
Defending Palantir
Mosley argues that Palantir's tools, like the all-seeing stones from The Lord of the Rings, can be used for good or evil. He insists the company's software has delivered 110,000 additional operations and reduced discharge delays. However, polling suggests over two-thirds of the UK public are concerned about Palantir's growing contracts, and 40% distrust it with NHS data.
Michael Gove, who worked with Mosley on Brexit planning, believes Palantir can provide "huge boons" if used wisely. But critics like Labour MP Rachael Maskell fear data could fall into the wrong hands, as seen with ICE targeting migrant communities. Mosley's challenge is to convince the public that he and Palantir are among the "goodies."
