When two Presidents, Dr. Zakir Hussain and Fakruddin Ali Ahmed, died in office, the then respective Vice-President, V V Giri and B D Jatti acted as President. The Vice-President Dr. S Radhakrishanan discharged the functions of the President in June 1960, when the then President Dr Rajendra Prasad was on a 15 days tour to the USSR and in July 1961, when Dr Rajendra Prasad was very ill. If the offices of both the President and Vice-President fall vacant by reason of death, resignation, removal etc, the Chief Justice of India or in his absence the senior most judge of the Supreme Court of India acts as President.
