The Vice-President of India serves a crucial role within the Union Executive, functioning primarily as the ex-officio Chairman of the Rajya Sabha, overseeing its proceedings. Elected by the members of both Houses of Parliament through Proportional Representation using the Single Transferable Vote, candidates must be citizens of India, at least 35 years old, and eligible to be a member of the Rajya Sabha. The tenure is five years, similar to that of the President. Notably, the Vice-President can also act as President in cases of vacancy or absence, ensuring continuity in governance. This position plays a pivotal role within the parliamentary system, harmonizing the relationship between the legislature and executive branches of the government.
