It’ll mean they cannot put more officers on the front line,” Mosley added. The US tech giant’s lawyers have now written to the Mayor’s Office for Policing and Crime (MOPAC) in a pre-action letter, notifying the mayor that they will press ahead with challenging Khan’s decision in court to overturn it, according to The Times.A company source for Palantir said Khan’s decision on its “values” was a “subjective assessment”.“We don’t take this decision lightly but we cannot stand by if procurement of our software is being politicised in this way,” the source said. Palantir, founded by American tech billionaire Peter Thiel, already holds contracts with other UK public sector bodies, including the NHS, the Ministry of Defence, and many regional police forces, such as in Bedfordshire and Leicestershire. The Met police had been eyeing an upgrade with the deal that would have used AI to change how crimes are investigated across London.The company has been used by organisations including the Israel Defence Forces and in immigration raids in the US.This follows Sir Michael Ellis KC, a former Tory attorney general under Liz Truss, raising concern that Khan’s decision to block the deal is “an extraordinary intervention, which may be susceptible to judicial review.” Ellis told the Times that the Mayor’s decision “appears to be based, at least in part, on Khan’s political sensibilities, namely how he views the values and ethics of this American company.” “If I were Palantir, I would be seeking legal advice as to whether Khan’s actions could be overturned by the courts,” Ellis added.Speaking to City AM on Monday, Khan claimed that shifting political dynamics in the US are actively driving tech talent and venture capital to the UK, arguing that London possesses structural and cultural advantages that “America doesn’t” as he seeks to position the capital against Silicon Valley. </div>
