Originally published in 1970, this book has a dual purpose. Firstly, it is a study of how Parliament works when the party whips are withdrawn. The author shows how backbenchers can create legislation of great importance; he demonstrates the obstacles, political and procedural to social reform; he relates the votes of MPs to their personal characteristics e.g. age, religion and occupation, and he argues that Parliament achieves a fresh vigour and authority when MPs think and act independently of party policy. Secondly, Parliament and Conscience analyses 6 major controversies in British society in the late 20th Century: the death penalty, homosexuality, abortion, theatre censorship, divorce and Sunday entertainment.
