Constitutional role of the Indian Constitution states "There shall be a President of India". Article 53(1)vests in the President the executive powers of the Union which are exercised either directly or through subordinate officers in accordance with the Constitution. Although the Constitution explicitly says that the president is the executive head of the state, real executive power is exercised by the Council of Ministers, headed by the Prime Minister.
