TL;DR

Matt Clifford, who drafted the AI action plan the government is still working through, has taken a senior post at Anthropic handling its relationships with governments beyond the United States. He keeps his chairmanship of Aria, the state-backed agency funding high-risk research, and will recuse himself there from anything touching his new employer.

The role, and the objections

Clifford’s job title is managing director for international affairs, covering Europe, the Asia-Pacific region and India as well as Britain. He was brought in as Sir Keir Starmer’s AI opportunities adviser in an unpaid capacity, stepped down six months later citing personal reasons, and before that represented Rishi Sunak at the 2023 safety summit — work that seeded the organisation now called the AI Security Institute.

The criticism was immediate and cross-party. Unlock Democracy’s chief executive Tom Brake, himself a Liberal Democrat MP for two decades, said the case shows advisers pose the same revolving-door problem as ministers, since detailed knowledge of a policy this sensitive hands a company an advantage soon after its holder leaves office. Chi Onwurah, who chairs the Commons committee covering science and technology, was more measured: she credited his contribution and defended movement between sectors, while calling the timing a matter of concern. The crossbench peer Beeban Kidron used the moment to argue for politics less entangled with the sector.

Anthropic’s reply was that Britain is one of dozens of governments the team deals with, and that hiring people who understand how government works is a requirement of the job in every market.

Why the timing draws attention

The pattern is established — Nick Clegg to Meta in 2018, Sunak himself later advising both Microsoft and Anthropic, George Osborne to OpenAI. What separates this appointment is that the company is preparing a flotation reported to value it near £1.5tn ($2tn), and that the copyright consultation Clifford publicly criticised while in post remains unresolved.

Looking forward

The Aria arrangement is the part worth watching. Recusal handles individual decisions cleanly enough; it does less about the broader question of a frontier lab’s incoming policy lead simultaneously chairing the body that distributes British moonshot research funding.
