As the system of governance and delivery of social welfare in the UK radically changes, this important new book argues that the extent of this change is such that it could be considered a fundamental transformation or even a revolution. It shows how a new public governance perspective has replaced the dominance of new public management, reflecting the increasingly plural and fragmented nature of public policy implementation. Drawing on examples across a range of policy areas it assesses how changes in social policy and governance interact in the delivery of the main areas of social policy and social welfare. The book will be essential reading for researches, students and policy makers.
