Shortlisted for the PSA WJM Mackenzie Book Prize 2025'Overall, this is an excellent book that makes a valuable contribution to our understanding of devolved governance in England. It is essential reading for those interested in the evolution of local governance and devolution in England, central-local relations and territorial politics more widely. The analysis underlines the validity of the much-quoted dictum, ‘devolution is a process, not an event’. I very much look forward to volume two on the second mayoral terms.'Paul Anderson, Regional & Federal Studies
