The book is suitable for undergraduate and postgraduate law students taking civil liberties courses, and also for students of other disciplines, such as politics and philosophy, who are studying civil liberties. The author provides an up-to-date analysis of the key issues, focusing on civil liberties and human rights that are directly affected by the powers of state agents, mainly the police and the security and intelligence services. In particular the focus is on recent and contemporary developments under the new Labour government, which amount to the most comprehensive state surveillance provisions ever introduced by a UK government.
