According to the Constitution of India, the office of the Vice President is the second highest constitutional post in independent India. The Vice President is the ‘ex-officio’ Chairperson of the Rajya Sabha.
The office of the Vice President in India is complementary to that of the President, in that, the Vice President takes over the role of the President in the latter’s absence.
In other words, the role of the Vice President is to assist the President in being the nominal head of the Republic of India. However, one must remember that the office of the President and the Vice President cannot be combined in one person, as per the Constitution of India.
