A political and public dispute has erupted in London after Mayor Sadiq Khan blocked a £50 million contract between the Metropolitan Police and US data analytics company Palantir. The deal was intended to use Palantir’s AI systems to support criminal investigations, but was halted due to concerns about procurement procedures and whether it aligns with public values.
Supporters see the decision as a safeguard for transparency, civil rights, and responsible use of public funds. Critics, including police representatives and Palantir, warn it could hinder modernization and efficiency improvements. The conflict highlights growing tensions around the use of AI in the public sector. Similar debates are also taking place in Germany. Some federal states use adapted Palantir-based systems such as HessenData or Vera, while others and security authorities like the BfA prefer European solutions.
