I have great pleasure in placing this book before the aspirants of the top administrate services. The book has been written to meet the growing requirement of the candidates appearing for the Civil Services Examination (Preliminary and Main) conducted by The Union Public Services Commission. In 2011 and 2013 the UPSC changed the pattern and Syllabus of the preliminary and main examinations, respectively. In both the changes, the scope of Indian Polity has been considerable increased. Hence this new edition of the book is more relevant now and is aimed to meet the expanded needs of the aspirants. This comprehensive volume would enable the readers to acquire a complete and detailed understanding of the subject. It covers all dimensions (constitutional, nonconstitution political and administrative) of the subject. My first hand experience of coaching the candidates for the Civil Services Examinations has been a great source of inspiration and has helped me immensely in writing this book. An efforts has been made to make the contents of the book relevant, authentic and upto date. The constitutional provision are explained in the light of the debates of the constituent Assembly of India as well as the judgement of the supreme Court and the high courts. I have also used tables to make the presentation more clear. The Appendices, Provide at the end of the book. Serve as a reference section. I welcome all constructive comments and concrete suggestion from the readers of this book.
