Aria will face an immediate leadership transition after Matt Clifford said he will resign as chair on 6 November, following warnings from senior MPs that his new job at Anthropic amounted to a conflict of interest. The decision was framed as a way to remove a governance concern created by his full-time role, which covers Anthropic’s engagement with governments outside the US.
Clifford said he was stepping down so the Anthropic position “doesn’t become a distraction from Aria’s incredible work,” and confirmed he would remain in post until 6 November while agreed safeguards remain in place. His employer had earlier said Clifford would recuse himself from any Anthropic-related business at Aria under arrangements agreed with the government.
The resignation followed public pressure from MPs including Chi Onwurah, Labour chair of the Commons science, innovation and technology committee, who described the appointment as a “clear conflict of interest” in correspondence with the AI minister. Other critics emphasised the poor optics of a senior government technology official moving directly into a leadership role at a major AI company.
Beeban Kidron, a crossbench peer and frequent critic of government AI policy, welcomed the move, saying, “If we are to rebuild trust in the government, we need to see a clear line between tech interests and those of citizens and the nation.” Campaigners and analysts framed the episode as another instance of the revolving door between Westminster and the private AI sector, noting a pattern of senior figures taking roles at leading tech companies in recent years.
Clifford has been a prominent figure in the UK tech ecosystem. He co-founded the venture capital firm Entrepreneurs First, has chaired Aria since 2022 and advised on national AI strategy, including work on the 2023 AI safety summit. He was appointed Keir Starmer’s AI adviser in January 2025 but stood down after six months for personal reasons.
The departure leaves Aria with immediate questions about how the initial appointment was approved and what conflict checks were completed. Opponents say the episode increases pressure on ministers and agencies to tighten rules governing moves between government and influential tech companies as the UK shapes its approach to AI regulation and safety.
