Who’s Who: English Devolution is a comprehensive guide to the individuals shaping regional leadership across England. From mayoral chiefs of staff and policy advisers to transport commissioners and cabinet members, the report maps the structures and staffing behind every combined authority.
Compiled from open sources, FOI responses and organisational statements, the guide captures how each authority operates – and how much visibility they offer. While some mayoralties share clear details on roles and responsibilities, others remain opaque, revealing a patchwork of approaches to transparency, structure and accountability.
This publication is essential reading for anyone engaging with England’s devolved institutions. It not only profiles key figures across regions, but also highlights the varied capacity and complexity of metro mayor leadership in 2025.
