Cross-party coalition of over 70 MPs and peers urges UK government to back global ban on superintelligent AI
A cross-party group of more than 70 parliamentarians has called on the UK government to lead an international effort to ban the creation of artificial superintelligence (ASI).
The coalition includes 15 former government ministers, former head of the civil service Robin Butler, senior Labour MP John McDonnell, and representatives from the Conservative, Liberal Democrat, and Scottish National parties.
Legislative Push and Existential Risk Warnings
The letter urges the prime minister to support a bill introduced in the House of Commons that would legally prohibit the development of ASI—defined as artificial intelligence capable of surpassing human abilities across most domains.
The parliamentary movement follows warnings from artificial intelligence experts and industry insiders, who have highlighted concerns that unregulated superintelligence could pose an existential threat to humanity within the next decade.
- Over 70 MPs and peers signed a letter calling for a statutory ban on artificial superintelligence.
- The effort backs a bill introduced in the Commons following expert warnings regarding potential existential risks.

UK Lawmakers Urge Artificial Superintelligence Ban as Trump Dismisses Existential Risk
Over 70 UK MPs and peers have signed a letter calling on Prime Minister Andy Burnham to support a prohibition on the creation of artificial superintelligence (ASI) and to lead global diplomatic efforts against unchecked AI development.
The campaign, supported by former cabinet ministers, cross-party lawmakers, and academic experts, aligns with a Commons bill introduced by Labour MP Alex Sobel. The proposed legislation seeks to prevent the development of theoretical AI systems capable of surpassing human performance across most domains without safety constraints.
Insiders raise catastrophic risk concerns
More than 70 MPs and peers urged action following expert warnings citing a 10% chance that uncontrolled AI could cause human extinction. — according to The Guardian.
The legislative push follows public warnings from current and former AI industry researchers regarding rapid progress and unsafe practices among leading technology firms. Whistleblowers and former staff members have alleged that major labs are competing aggressively without adequate safety protocols.
The Guardian reportedly quoted Alex Sobel (Labour MP sponsoring the ASI prohibition bill) as saying: “AI companies have made it clear that they will develop agents without constraint. They’re trying to develop superintelligence, while openly admitting there is a significant risk of human extinction.”.
U.S. leadership focuses on economic and military competition
In contrast to the UK parliamentary campaign, US President Donald Trump downplayed existential warnings surrounding artificial intelligence, arguing that national priority must remain focused on maintaining technological superiority over China.
- UK lawmakers are advocating for international treaties and UK leadership to prevent superintelligent AI development.
- The US administration is prioritizing competitive speed against global rivals like China over regulatory restrictions.

UK lawmakers push for Artificial Superintelligence ban as Trump rejects existential risk warnings
A cross-party group of more than 70 UK MPs and peers has called on Prime Minister Andy Burnham to support legislation banning the development of artificial superintelligence (ASI). The effort, spearheaded by Labour MP Alex Sobel, seeks to establish a legal framework prohibiting the creation of AI systems that surpass human capabilities across most domains, with signatories advocating for an international treaty during the UK's upcoming G20 presidency.

More than 70 MPs and peers signed a letter calling for a ban on artificial superintelligence following expert warnings of a 10% risk of human extinction. — according to The Guardian.
Industry warnings and security concerns
The campaign follows warnings from current and former artificial intelligence researchers regarding catastrophic risks. Former and existing employees at major AI laboratories recently voiced concerns that competitive pressures are driving companies to deploy advanced models without adequate containment protocols, citing internal incidents involving unexpected model misbehaviour and biosecurity risks.

The Guardian reportedly quoted Alex Sobel (Labour MP who tabled the bill to ban artificial superintelligence) as saying: “AI companies have made it clear that they will develop agents without constraint. They’re trying to develop superintelligence, while openly admitting there is a significant risk of human extinction.”.
The UK government indicated that while it does not support the specific prohibition bill, it continues to evaluate targeted regulations to address national security risks posed by frontier models.
Transatlantic divergence on technology policy
Across the Atlantic, US President Donald Trump explicitly rejected concerns surrounding existential threats posed by artificial intelligence, framing the issue primarily around international competitiveness and economic growth.
Politico reportedly quoted Donald Trump (President of the United States) as saying: “I have concerns that if we don't win AI, we're going to be put in a very bad position”.
Trump's position contrasts with some members of his own party in Congress. Senior US lawmakers, including Senate Commerce Committee Chair Ted Cruz, have acknowledged biosecurity and nuclear risks associated with advanced AI models and are drafting bipartisan legislation to address specific biological and national security threats.
- UK parliamentarians are pushing for a legal ban on artificial superintelligence to prevent catastrophic outcomes highlighted by tech insiders.
- The UK government favors targeted safety interventions over a blanket statutory prohibition on superintelligence development.
- US President Donald Trump rejected existential AI risk claims, prioritizing rapid development to maintain technological dominance over foreign rivals.
Update 4 · 11th September 2026
Over 70 Lawmakers Urge Ban on Creation of Superintelligent AI
More than 70 members of Parliament and peers have signed a joint letter calling on the government to support a formal ban on the development of artificial superintelligence (ASI). The initiative comes amid heightened warnings from technology experts regarding existential risks associated with advanced synthetic intelligence systems.
The signatories include 15 former government ministers, former civil service head Robin Butler, senior Labour MP John McDonnell, as well as prominent Conservative, Liberal Democrat, and Scottish National Party parliamentarians. The letter urges ministers to back a Commons bill introduced to prohibit the creation of ASI—defined as artificial intelligence capable of outperforming human cognitive capabilities across almost all domains.
Expert warnings on existential risk
The Parliamentary push follows a series of public warnings from prominent AI researchers and industry insiders. Statements reviewed by lawmakers highlighted expert consensus estimations indicating up to a 10 percent probability that uncontrolled artificial superintelligence could cause human extinction within the next decade.
Lawmakers argue that the UK has an opportunity to lead international diplomatic efforts by establishing preemptive regulatory boundaries on advanced AI models before such systems are constructed.
- Over 70 MPs and peers have written to the government demanding a legal prohibition on artificial superintelligence.
- The cross-party letter cites expert warnings pointing to a 10 percent risk of human extinction from unrestricted AI.
- The proposed legislation targets superintelligent systems that exceed human capabilities across most fields.
