Recalling the work of Niccolò Machiavelli, leading researcher Rinus van Schendelen distills the practices of successful lobbyists down to three basic principles: ambition, study, and prudence. Paying close attention to the special issues implicit in EU lobbying, this book illuminates the practice, its opportunities and pitfalls, and even its contributions to democracy. This revised edition has been strengthened with several new cases, insights and trends, and takes into account the new Treaty of Lisbon.
