This book is a good effort at highlighting the important features of the Indian Constitution. Each aspect is fully discussed, and coloured portions catch your eye to focus on special facts. The discussion of topics of political interest that occupy the public mind gives a different dimension and value to the book. It is a book worth reading to get the nuances of the Constitution with thorough understanding of the Indian political system.

The comprehensive coverage of the Constitution of India in this book is lucid and systematic. There are interesting details and up-to-date facts. The discussion of topics relevant to the political system adds to the overall worth of the book. And the language has been kept simple, making it all easy to understand.

Spectrum's Indian Polity is exhaustive and well researched. It covers not just the Indian Constitution but also its working and development over the years in the context of the political system in India. Compilation of information, especially in the chapters on separation of powers, statutory and regulatory bodies, and the working of the Indian Constitution, will be very helpful for students as well as academicians. The flow of the language is easy to understand and the discussion columns at the end of chapters enhance the book's relevance today. Perhaps, there could have been more discussion of topics in the chapter on Federalism and a critical analysis of how the local government is actually working in India. Overall, I can say that it's been long since such a comprehensive compilation of information on Indian Polity in a single book has been available.

This is an excellent book designed to give a thorough understanding of Indian Polity and its dynamics. The book provides precise, systematic, and practical explanations on various aspects of Indian Polity. The special feature of the book is that issues of topical interest are discussed at the end of each chapter. Besides being useful for preliminary and mains, the comprehensive and analytical approach of the book makes it very useful for preparation for the Personality Test of the Civil Services Examination. In a nutshell, it is a must-read book on Indian polity for aspirants preparing for any competitive exams.

Precise, well-researched, relevant, comprehensive. These are some of the features of Spectrum’s ‘Indian Polity’ that stood out for me. All the topics of Indian polity are covered in the book in a detailed manner. The Discussion part given at the end of each chapter is very useful for Mains answer writing. The Supreme Court Judgments, Quotations of Important Political Thinkers, examples from history, etc., make the book very helpful for note making and answer writing.

Aspirants are usually aware of only Spectrum’s ‘A Brief History of Modern India’ but they should give a chance to their other books as well, especially this book on Indian polity.

I am sure this will also become a favourite of UPSC aspirants.
