Palantir accuses Sadiq Khan of 'putting politics over public safety' after 50m Met deal blocked

London Mayor Sir Sadiq Khan has been accused of putting politics over public safety after blocking a £50m contract between the Metropolitan Police and US tech firm Palantir. Scotland Yard had been in talks to use the company's artificial intelligence to speed up criminal investigations. Palantir's UK chief executive Louis Mosley also said the decision would give hostile states and criminals an advantage. The Met has previously warned it will have to cut officer numbers if the deal does not proceed. Palantir, founded by tech billionaire Peter Thiel, a prominent donor to US President Donald Trump, already holds contracts with other UK public sector bodies.
