Palantir to sue Sadiq Khan over blocked £50m Met police contract

Palantir intends to sue the London mayor, Sadiq Khan, after he blocked a contract between the US spy-tech firm and the Metropolitan police.

The Met had planned to use Palantir’s software to automate intelligence analysis in criminal investigations, until Khan intervened in late May, sparking a row between the UK’s largest police force and the mayor’s office.

Khan said there had been a breach of procurement rules in the contract and suggested Palantir had been the only contender.

Now the Times has reported that Palantir’s lawyers have written to the Mayor’s Office for Policing and Crime saying they intend to challenge the decision in court. Khan’s office confirmed they had received the letter. Palantir declined to comment for this article.

A spokesperson for Khan’s office said: “The Met did not present its procurement strategy as required and the Met only fully engaged with one potential supplier: Palantir.”

They added the decision was not made on the basis of “values or political considerations” but rather the procurement process “did not adequately demonstrate value for money for Londoners”.

The Met’s potential deal with Palantir, worth £50m, is one of a series of agreements between the US software company and UK government bodies now under fire amid a wave of mounting distaste over the company’s public ideological statements.

On Tuesday morning, the technology secretary, Liz Kendall, confirmed the government was conducting a full review of the NHS contract with Palantir, assessing whether to extend the £330m deal or activate a break clause that would allow it to stop using the company’s services in early 2027.

Last week, a parliamentary committee urged the government to trigger a break, calling Palantir’s presence an “unacceptable point of weakness” in a public sector increasingly reliant on a handful of US tech firms.

In April, Palantir published a mini-manifesto on X extolling the benefits of US power and implying some cultures were inferior to others, in what one MP called “the ramblings of a supervillain”.
