Explanation:

The Prime Minister of India is the chief executive of the Government of India. In India's parliamentary system, the Constitution names the President as head of state de jure, but his or her de facto executive powers are vested in the prime minister and their Council of Ministers. Appointed and sworn-in by the President, the prime minister is usually the leader of the party or alliance that has a majority in the Lok Sabha, the lower house of Parliament of India.
