A joint session of the Parliament of India is convened when there is a deadlock between the Lok Sabha and Rajya Sabha on a bill, particularly a Money Bill or other legislative matters.
Step 2: Presiding Officer
The Speaker of Lok Sabha presides over the joint session.
Step 3: Role of others
- The Vice President is the ex-officio Chairperson of Rajya Sabha but does not preside over joint sessions.
- The President and Prime Minister do not preside over parliamentary sessions.
Therefore, the correct answer is The Speaker of Lok Sabha.
