The Prime Minister is the real executive authority in the Union Executive and acts as the head of the government. The Prime Minister leads the Council of Ministers and is responsible for policy formulation and decision-making. He or she acts as a link between the President and the Council of Ministers and coordinates the functioning of various ministries. The Prime Minister advises the President on appointments, administration, and important national matters. The effectiveness of the Union Executive largely depends on the leadership, coordination, and authority exercised by the Prime Minister.
