US data analytics company Palantir has notified the Mayor of London that it intends to take legal action after Sadiq Khan blocked a £50 million contract with the Metropolitan Police, the Times has reported.
The Met had planned to use Palantir's software to automate intelligence analysis in criminal investigations, until Khan intervened in late May. The Mayor's Office for Policing and Crime concluded that the Met had only engaged with one potential supplier, had failed to present its procurement strategy to the deputy mayor for approval as required, and had not adequately demonstrated value for money.
The lawsuit threat lands amid wider scrutiny of Palantir's UK public sector relationships. Technology secretary Liz Kendall confirmed the government is conducting a full review of Palantir's £330 million NHS contract, assessing whether to extend it or activate a break clause in early 2027. A parliamentary committee last week urged the government to trigger that break, calling Palantir's presence an "unacceptable point of weakness" in a public sector increasingly dependent on a small number of US technology firms.
