The UK government announced measures to strengthen defences against AI risks on 12 October 2026. Two pilots helped identify and fix over a thousand potential cyber vulnerabilities across government systems. The government will extend the programme, explore stronger protections through the Cyber Security and Resilience Bill and the wider regime, and prepare for serious incidents involving autonomous AI agents. In a speech at Imperial College London the same day, AI minister Kanishka Narayan said the AI Security Institute is evaluating the latest models, including Gemini 4 Argon, and that Security Minister Dan Jarvis will lead a cross-government programme against cyber attacks, including those using AI.

Why it matters

The UK is using frontier AI to find weaknesses in government systems before attackers do, and is preparing a response to incidents caused by autonomous AI agents.
