The Constitution of India establishes a parliamentary system of government where the President is the nominal head of the State, the Prime Minister is the real executive authority, and the Parliament is the supreme legislative body.

Together, they ensure the smooth functioning of democracy. This framework is inspired by the British parliamentary model but adapted to Indian needs.

It provides for a clear division of powers and responsibilities, ensuring a balance between the executive, legislature, and the ceremonial head of state.

This system not only guarantees democratic accountability but also strengthens the principle of collective responsibility in governance.
