This book provides a succinct overview of the development of the civil service since the Second World War. Adopting a broad, historical approach, it assesses the changes in organization, structure and management of the Whitehall machine, alongside the continuities in the policy and practice of public administration. Kevin Theakston draws on the full range of recent scholarship, documents in the Public Record Office, and the many postwar offical investigations and reports to provide a balanced analysis of the key themes and issues. The book will be welcomed by all interested in the development of public policy and administrations, and post--war British politics in general.
