India has a parliamentary arrangement of government based mainly on that of the United Kingdom (Westminster system).
The elected representatives is the Parliament. It is bicameral, consisting of two houses: the directly-elected 545-member Lok Sabha (“House of the People”), the lower house, and the 250-member indirectly-elected and selected Rajya Sabha (“Council of States”), the upper house. The Indian parliament enjoys parliamentary superiority.
The executive is torn between a largely ceremonial head of state (the President of India). The President enjoys all legitimate constitutional powers, but exercises them merely on the advice of the actual executive, the head of government (Prime Minister of India) and his or her Council of Ministers (the cabinet), which enjoy all genuine powers and make significant policy decisions.
All the members of the Council of Ministers as well as the Prime Minister are members of Parliament. If they are not, they must be chosen within a period of six months from the time they assume their respected individual office. The Prime Minister and the Council of Ministers are accountable to the Lok Sabha, alone as well as cooperatively.
