When Matt Clifford took a full-time job at Anthropic earlier this month, he said he would keep his other job too — chair of ARIA, the UK government's high-risk research agency. This week he changed his mind.

Clifford wrote the AI Opportunities Action Plan that the government adopted in full, and served as the Prime Minister's adviser on AI until mid-2025. On Monday he announced he will step down as ARIA's chair, staying in post only until 6 November "with appropriate safeguards against potential conflicts in place."

"I have decided to step down to ensure my new role at Anthropic doesn't become a distraction from Aria's incredible work," he said.

The conflict he was asked about

Clifford's new role at Anthropic is managing director of international affairs, based in London, leading the company's engagement with governments outside the United States — including the UK. That is the crux of the objection: the person who shaped how Britain buys and regulates AI would, while still chairing a state research agency, be representing one of the largest AI firms to that same government.

Chi Onwurah, the Labour MP who chairs the Commons Science, Innovation and Technology Committee, had called the arrangement a "clear conflict of interest" and raised it with the AI minister. Clifford's resignation is widely read as a response to that pressure.

The questions that outlast the resignation

Stepping down did not settle Onwurah's concern. She said it remains unclear "how this situation arose, what conflict of interest assessments were undertaken and what safeguards are in place to protect confidence in Aria's governance." Anthropic has said Clifford will recuse himself from any Anthropic-related business at ARIA under an arrangement agreed with the government — but that recusal has to hold over the very period, until November, that his departure was meant to resolve.

Not a one-off

The movement is now a pattern. Former Prime Minister Rishi Sunak has taken roles with Anthropic and Microsoft; former Chancellor George Osborne works for OpenAI; Nick Clegg ran global affairs at Meta until 2025. Senior figures moving between government and the AI industry that government is trying to regulate has become ordinary — which is exactly why the governance question Onwurah is asking matters beyond one appointment.

This is the coda to a story we covered last week, when Clifford was still planning to hold both roles. The optics have changed; the underlying question has not.
