Matt Clifford to quit ARIA chair before Anthropic role creates conflict

Matt Clifford will step down as chair of the UK's Advanced Research and Invention Agency, reversing a plan announced days earlier to hold that job alongside a new role at Anthropic. He will stay at ARIA until November 6, 2026, at the request of business and science secretary Jonathan Reynolds, to give the government time to run a search for his replacement.

The reversal took five days. On September 2, Clifford announced on X that he was joining Anthropic as managing director for international affairs, based in London and leading the company's engagement with governments across Europe and Asia-Pacific. At the time he said he intended to keep his ARIA chair role too, citing unspecified safeguards to manage the overlap.

That plan did not survive contact with Parliament. Dame Chi Onwurah, the Labour MP who chairs the Commons Science, Innovation and Technology Committee, wrote to AI minister Kanishka Narayan calling the dual-role arrangement a clear conflict of interest. Her question was pointed: what conflict assessments had been carried out, and who had signed off on letting Clifford hold both jobs in the first place. ARIA disburses roughly £800 million in public funding, much of it into AI-related and AI-enabled research, work that sits squarely alongside Anthropic's own commercial and policy interests.

Once Clifford's resignation was announced, Onwurah welcomed it, saying the conflict had been addressed through his decision to step down. That statement closes the immediate controversy without answering her original question about how the arrangement was cleared in the first place. Neither the government nor the Cabinet Office has said publicly who approved the initial dual-role plan or what review, if any, took place before Clifford's September 2 announcement.

The timing matters beyond optics. Clifford was reappointed to ARIA's chair in September 2025 for a five-year term running to August 2030, meaning he was barely a year into that mandate when he announced his departure. He was also the agency's founding chair, having taken up the post in August 2022 under the ARIA Act 2022, the legislation that created the £800 million research body with a mandate to fund high-risk, high-reward science.

Clifford's move to Anthropic is pointed for a second reason: he helped write the policy environment that frontier AI labs now operate in. As an unpaid adviser to Rishi Sunak he helped organize the 2023 UK AI Safety Summit, and under Keir Starmer he authored the AI Opportunities Action Plan, published January 13, 2025, whose 50 recommendations the government endorsed in full. Among them was a push to loosen UK copyright rules toward the EU's approach, a change that would make it easier for AI companies to train models on copyrighted material and that drew sustained objections from creative industries.

ARIA's chief executive, Ilan Gur, will need to steer the agency through the eight-week handover to November 6 while the search for a new chair gets under way, with the agency's AI-heavy grant portfolio continuing to run in the interim. Anthropic, for its part, has framed the hire around bringing industry, governments and civil society together on AI policy, a description that will sit next to Clifford's copyright recommendation as scrutiny of the appointment continues.
