January 14, 2026, 3:32 PM EST. UK police officials admitted that a decision to ban football fans relied on Copilot AI "hallucination," not human intelligence. Guildford acknowledged in a January 12 letter that the erroneous result for the West Ham v Maccabi Tel Aviv match arose from a misuse of Microsoft's Copilot, after initially saying Google identified the match. In the House of Commons, Home Secretary Shabana Mahmood criticised the force for "confirmation bias," saying Amsterdam reports were exaggerated or untrue. She called the claim that AI tools were not used in intelligence reports a failure of leadership, and said Guildford no longer has her confidence. Conservatives joined calls for his resignation; MPs demanded more detail on AI misuse and policies, including through FOI requests.
