Synopsis The present publication attempts to profile in good detail the constitutions of the four countries, namely the U.K., U.S.A., Switzerland and China. The analyses are of great relevance as the diversity of political vision is reflected in the fact that while the U.S. A and U.K. has a two party system, whereas China has only one party. Switzerland is unique because it has been a neutral country in times of war. The book presents details of federalism, and all the arms of the constitutional system namely, the legislature, the executive, and the judiciary. While all aspects of the working of the constitution, interpretation of various clauses thereof from time to time and amendments have been dealt with in necessary contexts, the book also includes such vital discussions as direct democracy in Switzerland, its cantonal governments, and other local units of administration and the new 1998 constitution of that country. Also included are the most important texts of the four constitutions. It is thus evident that the detailed discussion and profiles contained in the publication will be immense use to students of Political science, in particular comparative Governments and also to academics and researchers in this vital area of modern politics and political evolution.
