Book excerpt: Set against the backdrop of the London 2012 Olympic and Paralympic Games, this book examines the impact on public policy from broader political decisions taken in relation to Olympic- and Paralympic-related policy. It considers the major political justifications for hosting these global sports events, evidence for their expected impacts, and topical issues including environmental protection and sustainability, the use of technology, and political protest. The book will be essential reading for anyone with an interest in sport policy and politics, and how broader political decisions come to impact on the development of Olympic and Paralympic sport. This book was published as a special issue of the International Journal of Sport Policy and Politics.
