LONDON, June 9 (Parliament Politics Magazine) – Palantir is preparing legal action against London Mayor Sadiq Khan following his decision to block a £50 million contract intended for the Metropolitan Police. The US-based software firm, known for its data analysis and intelligence tools, aims to challenge the intervention in court after City Hall prevented the agreement from moving forward in London.
Dispute Over Procurement Rules
The Metropolitan Police had planned to utilize Palantir software to automate intelligence analysis for criminal investigations. This two-year, £50 million deal was halted in late May after Sadiq Khan intervened, citing significant concerns regarding the procurement process. According to the Mayor’s office, the police force did not present a formal procurement strategy as required by policy.
City Hall maintains that the Metropolitan Police failed to engage with multiple potential suppliers, effectively treating Palantir as the sole candidate for the project. Officials stated that this approach did not demonstrate adequate value for money for taxpayers. While the Metropolitan Police characterized the cancellation as disappointing and warned that it could hinder modernization efforts, the Mayor’s office asserts the decision was strictly procedural.
Legal Challenge Formalized
Lawyers representing Palantir have now written to the Mayor’s Office for Policing and Crime confirming the company’s intent to challenge the veto in court. A spokesperson for Sadiq Khan confirmed that the office received the pre-action letter. The software firm has declined to provide further comments regarding the specific legal arguments it plans to present.
The dispute highlights a growing tension between major US technology firms and UK public bodies. While Palantir argues that the intervention prioritizes political optics over public safety, City Hall officials emphasize that all contracts must adhere to rigorous competition standards. The situation has intensified debates regarding the influence of foreign technology providers within domestic law enforcement.

Broader Scrutiny of Tech Contracts
The clash is occurring alongside a wider government review of existing agreements with Palantir. Technology Secretary Liz Kendall recently confirmed that the government is conducting a full assessment of the company’s £330 million contract with the National Health Service. This review will determine whether the government should extend the deal or activate a break clause to terminate services in 2027.
Concerns regarding the firm have been echoed in various parliamentary circles. A committee recently described the public sector’s reliance on a small number of US tech companies as an unacceptable point of weakness. Various lawmakers have raised questions about the company’s public ideological statements, which some critics describe as incompatible with the values of British public institutions.
Differing Views on Corporate Ties
Political friction surrounding the company is not limited to procurement processes. Critics frequently point to the firm’s origins and its high-profile leadership. Founded by Peter Thiel, the company has faced intense scrutiny from activists and politicians over its historical contracts with international military and intelligence organizations. These connections have fueled public debate regarding whether such companies should hold sensitive roles within the UK’s essential services.
Labour MP Clive Lewis voiced concerns during the ongoing debate, stating: “You look at other countries who have stayed well away from Palantir – France and Germany. They have had the same briefings every other European country has, which is to allow a company like that, with the close connections it has to unsavoury political views, is asking for trouble.”
As the legal proceedings begin, the case will likely serve as a test for how London manages its relationships with large-scale technology partners. Whether the dispute results in a reversal of the blocked contract or establishes a new precedent for procurement oversight remains to be determined by the courts.
