The Metropolitan Police's controversial £50 million deal with US AI company Palantir has sparked a debate that goes to the heart of how public services should use artificial intelligence. As the UK's largest police force faces a £125 million funding shortfall and must cut 1,150 posts, it sees AI as a way to replace some human labour. Scotland Yard wants to use Palantir's systems to analyse human intelligence reports, emails, phone records, and other digital evidence, but critics question the cost and ethics.
AI as a Fiscal Escape
Police chiefs are turning to technology to escape a fiscal bind. The Met is not alone: forces like Bedfordshire and Leicestershire already use Palantir tech, and the Home Office is pushing for wider AI adoption. Home Secretary Shabana Mahmood has called for police to "ramp up use of AI" at "pace and scale." Labour has established a national Police AI centre and is deploying AI in the NHS, military, and justice system. However, the government lacks its own AI systems, and the companies that can help are increasingly controversial.
Political and Public Backlash
London Mayor Sadiq Khan blocked the deal citing a "clear and serious breach" of procurement rules and concerns about using public money to support firms that act contrary to London's values. Palantir's leaders, including co-founder Peter Thiel and CEO Alex Karp, have made controversial statements. Thiel said the NHS makes people sick, while Karp called post-WWII disarmament of Germany and Japan an "overcorrection." Many US AI providers face public distrust due to associations with big tech and Donald Trump. Palantir, with contracts for Trump's ICE crackdown, Israel's military, and the US defence department, has become a symbol of big tech's dark side.
When Palantir recently provided an AI surveillance system to root out corrupt officers at Scotland Yard, rank-and-file police were appalled, calling it "Big Brother" and reporting sleepless nights. The Metropolitan Police Federation described it as "unchecked use of a controversial AI provider to spy on every single one of our colleagues … not proportionate, just or proper." Rebuilding trust will take time.
Lack of Alternatives
Police leaders concluded that Palantir is the only company that can supply what they need, though a Scotland Yard insider said smaller British firms could provide aspects of the service piecemeal. Professor Alan Woodward of the University of Surrey noted that Palantir has a far greater range of tools than most competitors. British companies cannot yet compete, but AI is becoming critical infrastructure, and the UK needs independence. "We have the expertise," Woodward said. "What is needed is the development of the businesses. That's where Palantir won big. They had US government funding."
