Chi Onwurah, chair of Parliament's Science & Technology Committee, compared AI's opacity to mortgage-backed securities: 'The last time experts didn't understand what they made, it was the mortgage-backed securities that caused the financial crisis.' She called for barring companies that refuse to cooperate with the UK AI Security Institute from selling enterprise software in the UK.

Labour MP Alex Sobel tables ASI ban bill in UK Commons; targets AI exceeding human performance

What This Means
The cross-party letter from 70+ UK MPs and peers calling on PM Burnham to back an ASI ban bill marks the most significant legislative move on existential AI risk in UK parliamentary history. Unlike earlier UK AI governance debates focused on bias and economic harm, this directly targets development of artificial superintelligence — AI that outperforms humans across most domains. The government's partial acknowledgment of AI national security risks, even while rejecting the ban, suggests the existential framing is gaining policy traction. Combined with Bernie Sanders' parallel effort in the US, September 2026 appears to be a coordinated transatlantic inflection point for legislative action on AI existential risk.
