IndiaIndiaGovernment & politics
IndiaIndia
India is a Westminster-style parliamentary democracy with a federal structure. The President is the constitutional head of state, but the office is largely ceremonial — real executive power rests with the Prime Minister and the Council of Ministers, who are drawn from and answerable to the elected Lok Sabha. The PM is usually the leader of the party or coalition that commands a majority in the lower house. States hold significant devolved powers, and an independent judiciary headed by the Supreme Court can strike down laws that violate the constitution.
Japan
Japan is a constitutional monarchy in which the Emperor is defined by the postwar constitution as the 'symbol of the State' with no governing power at all. Executive authority lies with the Prime Minister, chosen by and accountable to the elected House of Representatives, and the Cabinet. Japan's constitution famously renounces war, and the military (the Self-Defense Forces) is under strict civilian control.
