Guest Article: Alex Sobel MP writes about why the UK needs an AI kill switch to remain sovereign and how his amendment to the Cyber Security and Resilience Bill would provide just that.
I rise today to speak in strong support of the amendment before the House — an amendment that would grant the Government the power to direct the shutdown of dangerous AI systems or compromised data centres in the event of an AI‑related security emergency.
This is not a theoretical debate. It is a matter of national security, public safety, and sovereign control over the digital infrastructure upon which modern Britain depends.
Just weeks ago, the AI company Anthropic took the unprecedented step of withholding wide release of its newest model, Mythos, after discovering that it possessed advanced cyber‑offensive capabilities. Mythos was able to identify vulnerabilities in every major web browser and operating system — including weaknesses that cybersecurity experts had not uncovered in decades. The company itself warned that the model posed a national security risk.
If private developers are now producing systems capable of discovering zero‑day vulnerabilities at scale, autonomously, and at machine speed, then we in Parliament must confront a simple truth: our current legal framework is not built for the world we have entered.
At present, the United Kingdom has no statutory mechanism to shut down a dangerous AI system.
No emergency protocol.
No designated authority.
No power to compel the shutdown of a compromised data centre hosting critical national infrastructure.
Madam Deputy Speaker, that is a sovereignty gap.
A security gap.
And a preparedness gap.
Our hospitals, our financial institutions, our energy grid, our transport networks — all rely on cloud‑based systems that could be compromised by an AI‑driven cyberattack spreading faster than any human response team could contain. The consequences of such an attack would be devastating. And as the MI5 Director General warned in 2025, we must prepare for “potential future risks from non‑human, autonomous AI systems which may evade human oversight and control.”
Yet today, if such a system emerged on UK soil, the Government would be powerless to act.
This amendment changes that.
It provides a last‑resort kill‑switch power — a sovereign safeguard enabling the Government to intervene decisively when an AI system threatens national security or when a data centre becomes the vector of an uncontrollable cyber incident.
Let me be clear: this is not a tool for routine use.
It is not a tool for political convenience.
It is a tool for emergencies — for the moments when delay would mean disaster.
And it is not only about today’s threats. It is about tomorrow’s.
Leading AI researchers, intelligence officials, and over 100 cross‑party parliamentarians have warned that the development of superintelligent AI — systems vastly more capable than humans and able to escape human control — would pose an unprecedented national security risk. If credible evidence emerged that such a system was being developed in a UK data centre, the Government currently has no clear authority to intervene.
This amendment closes that gap. It ensures that the United Kingdom retains the sovereign ability to act before a threat becomes irreversible.
Madam Deputy Speaker, Parliament has a responsibility to anticipate danger, not merely react to it. We cannot wait for an AI‑driven cyberattack to cripple the NHS, or for an autonomous system to compromise our critical infrastructure, before we decide that emergency powers were necessary after all.
Preparedness is not alarmism.
Preparedness is governance.
This amendment is a proportionate, necessary, and common‑sense measure to protect the British public and safeguard our national security in an era of rapidly advancing AI capabilities.
I urge Honourable Members across the House to support it.
Britain must not be left powerless in an AI emergency.
Many devices need the capacity to run without cloud computing. For example, nuclear power plants, hydroelectric, dams, and even your homes heating system need to be able to operate without cloud computing. That is to say we need to be able to shut down data centers and cloud computer without the risk of creating chaos.
I 100% agree. And I just WISH our congress would get this message and move proactively. But, apparently, that's not in the cards with this administration.

We all need AI Kill Switches
Good idea. Now describe how it could be implemented and succeed.
I 100% agree. And I just WISH our congress would get this message and move proactively. But, apparently, that's not in the cards with this administration.
