London Police Chief Warns of Cuts After Mayor Blocks Palantir AI Deal

The Metropolitan Police is preparing for potential cuts to frontline services after London Mayor Sadiq Khan blocked a planned £50 million contract with Palantir, the U.S. technology firm known for its artificial intelligence capabilities.

Metropolitan Police Commissioner Sir Mark Rowley warned in a report scheduled for presentation at the London Policing Board that the force now faces "stark" choices that will mean it can "achieve less for London's communities." The department had been negotiating with Palantir to deploy AI technology aimed at accelerating criminal investigations and identifying corrupt officers within the force.

The blocked contract

Scotland Yard proposed a £25.3 million contract with Palantir UK for the 2026-27 fiscal year, with an optional one-year extension worth an additional £24.8 million. The AI system was intended to automate time-consuming tasks such as searching through reports and phone data during investigations.

By implementing this technology, the Met expected to eliminate 500 positions while maintaining service levels. However, the Mayor's Office for Policing and Crime (MOPAC) rejected the proposal, stating the Met had not adequately demonstrated value for money. MOPAC also noted that the Met failed to present its procurement strategy for approval as required, though the police force maintains its process was "legally and commercially compliant."

Financial pressures mount

The decision comes as the Metropolitan Police grapples with a £125 million funding gap in the upcoming financial year. Over the past two years, the force has already reduced its workforce by 3,300 officers and staff.

Sir Mark Rowley indicated that without the anticipated AI-driven efficiencies, the 500 planned job reductions will "directly hit the delivery of policing to London's communities." The commissioner said the force is now evaluating options that range from stopping services entirely to reducing team sizes or changing service delivery methods.

While a new procurement process could potentially resolve the situation, Sir Mark warned it would likely take "at least a number of months" to meet MOPAC's requirements.

Why it matters

This dispute highlights the growing tension between public sector AI adoption and procurement oversight. As police forces across the UK face budget constraints, they're increasingly looking to automation as a path to efficiency. But the London case demonstrates that enthusiasm for AI must be balanced against rigorous value assessments and proper governance processes—especially for contracts worth tens of millions of pounds. The outcome will likely influence how other UK public bodies approach large-scale AI procurements.

Palantir's track record and controversy

A Palantir spokesperson defended the company's work with UK law enforcement, noting that its software helped Bedfordshire police identify 1,000 women whose partners had histories of domestic violence in a single year. The company also cited a pilot project with Scotland Yard that used AI to detect serious corruption within the force.

Founded by billionaire Peter Thiel, Palantir has faced criticism for its contracts with U.S. Immigration and Customs Enforcement and the Israeli military, prompting calls for public bodies to consider ethical factors when awarding contracts. MOPAC acknowledged concerns around the firm's values and ethics, though legally such considerations cannot be the basis for contract refusal.

According to reporting by the Times, Palantir intends to sue the mayor over the blocked deal.

A spokesperson for Mayor Khan emphasized support for police use of modern technology but stressed the importance of following correct procurement processes and ensuring value for taxpayers, particularly given tight budgetary constraints.
