Matt Clifford Steps Down as ARIA Chair Over Anthropic Conflict
Matt Clifford used to lead a UK government agency called ARIA.
ARIA funds projects involving advanced science and technology.
Clifford then accepted a full-time job at Anthropic, an AI company based in San Francisco.
His new job involves working with governments, including the UK.
Some lawmakers worried that holding both jobs would create a conflict of interest.
Clifford first planned to keep leading ARIA, but he later resigned as chair.
Chi Onwurah said the resignation solved the conflict.
Tom Brake still warned that private companies could gain useful government knowledge when officials move into industry.
Matt Clifford resigned as chair of the UK government’s Advanced Research and Invention Agency after joining Anthropic full time.
Clifford will lead Anthropic’s engagement with governments outside the United States, including the United Kingdom.
He had initially planned to remain ARIA chair despite concerns that his new role created a conflict of interest.
Chi Onwurah, chair of the House of Commons Science, Innovation and Technology Committee, called the situation a clear conflict.
Unlock Democracy chief executive Tom Brake warned that Clifford’s move could weaken the government’s position on precautionary AI policy.
