The federal government comprises three branches
• Executive: The President of India is the head of state and is elected indirectly by a national electoral college for a five-year term. The Prime Minister of India is the head of government and exercises most executive power. Appointed by the president, the prime minister is by convention supported by the party or political alliance holding the majority of seats in the lower house of parliament. The executive branch of the Indian government consists of the president, the vice-president, and the Council of Ministers—the cabinet being its executive committee—headed by the prime minister. Any minister holding a portfolio must be a member of one of the houses of parliament. In the Indian parliamentary system, the executive is subordinate to the legislature; the prime minister and his council are directly responsible to the lower house of the parliament.
