Political Corruption [PDF ebook] 
In Beyond the Nation State

This book, combining scholarship with readability, shows that political corruption must itself be analysed politically. Spectacularly corrupt politicians – the exception rather than the rule – are usually symptoms, not causes, and much political corruption is simply normal politics taken to excess. But in a world in which anti-corruption strategies themselves are often thinly disguised examples of political corruption, the ways in which political systems address their own corruption are as varied and fascinating in character as crucial to comprehend. A valuable read for anyone studying social science disciplines such as politics, international relations, sociology, anthropology, criminology and public policy. As well as the global community of anti-corruption activists, professional politicians, police, business people and lawyers.
