Matt Clifford — Co-Chair at UK AI Safety Institute

While the source text confirms that Matt Clifford is associated with the UK AI Safety Institute (evidenced by the FOI release 'FOI2024-00388: Declarations of interest for Matt Clifford and Saul Klein'), it does not provide any information about his specific role (Co-Chair), organizational position, or start date (2023-06). The source document is a government webpage listing publications and documents, not a personnel directory or organizational chart. To verify the specific role and start date claims, a different source would be needed.
