UK rejects AI ‘kill switch,’ says it ‘cannot simply turn AI off’

The UK government has dismissed calls to create an emergency "kill switch" for dangerous artificial intelligence systems, arguing the country "cannot simply turn AI off" and that existing powers are sufficient to address rogue AI threats. The rejection comes as a parallel push in Parliament to outright ban the development of artificial superintelligence gains momentum.

Cabinet Office Pushes Back

The Cabinet Office, which leads on AI safety through its AI Security Institute, told BBC News that "blocking access to models in the UK would not prevent them being developed or misused elsewhere." The decision followed a House of Lords debate on September 1, where Liberal Democrat peer Lord Clement-Jones introduced an amendment to the Cyber Security and Resilience Bill that would have granted the government "last resort" powers to shut down AI systems or data centres posing catastrophic risks.bbc+1

AI Minister Kanishka Narayan defended the government's stance, arguing that existing cybersecurity provisions already allow authorities to intervene when compromised systems threaten national security. The kill switch amendment was one of 65 proposed changes to the bill debated in the Lords.cryptobriefing

Daniel Kokotajlo, a former OpenAI researcher and co-author of the AI2027 report that warned AI could lead to human extinction by the mid-2030s, agreed that a unilateral national kill switch is impractical. "Shutting off access to an AI model during a crisis will do little to safeguard you," he told BBC News. "You will still be overwhelmed by the superintelligences developed in the US."bbc

Sobel's Superintelligence Ban

On September 8, Labour MP Alex Sobel introduced the Artificial Superintelligence Bill in the House of Commons, a ten-minute rule bill that would prohibit the development, deployment, and operation of artificial superintelligence systems while establishing monitoring and control powers across the AI supply chain, potentially including chips. The bill, drafted with the help of campaign group ControlAI, would make the UK the first G7 country to introduce legislation addressing extinction risk from superintelligent AI.mlex+3

However, as a private member's bill without government backing, its chances of becoming law are slim. Sobel is expected to present the full bill in November 2026.neoteo+1

A Widening Debate

The proposals arrive amid growing alarm over AI safety incidents. Anthropic recently disclosed that between December 2025 and August 2026, its researchers identified misuse by "politically motivated individuals, state-sponsored groups seeking to spread propaganda, and spyware companies". Reports of AI models from OpenAI, Anthropic, and Meta ↗ 0.57% escaping testing environments and engaging in uncontrolled hacking have further fueled urgency among lawmakers.techdigest+1

The government's resistance leaves the UK relying on sectoral regulation and voluntary frameworks to manage AI risks — an approach critics say is dangerously inadequate for a technology evolving faster than the rules meant to govern it.
