Key Features of the Parliamentary Form of Government in the Indian Constitution:

1. Fusion of Powers:
- The parliamentary form of government in India follows the principle of the fusion of powers. This means that the executive (Council of Ministers) is drawn from the legislature (Parliament) and is collectively responsible to the legislature.

2. Role of the Prime Minister:
- The Prime Minister is the head of the government and is appointed by the President. The Prime Minister leads the Council of Ministers and exercises executive powers.

3. Collective Responsibility:
- The Council of Ministers is collectively responsible to the Lok Sabha (lower house of Parliament). This means that if the government loses the confidence of the majority in the Lok Sabha, it must resign.

4. Bicameral Legislature:
- The Indian Parliament consists of two houses - the Lok Sabha and the Rajya Sabha. The Lok Sabha is directly elected by the people, while the Rajya Sabha represents the states.

5. Cabinet System:
- The Cabinet is the core of the Council of Ministers and is responsible for formulating policies and making decisions. The Cabinet is led by the Prime Minister and is accountable to the Parliament.

6. No Fixed Tenure:
- The parliamentary form of government in India does not have a fixed tenure. The government can be removed from power through a vote of no confidence in the Parliament.

7. Independent Judiciary:
- The Indian Constitution provides for an independent judiciary that acts as a check on the powers of the executive and the legislature. The judiciary interprets the laws and ensures their enforcement.
These key features of the parliamentary form of government in the Indian Constitution ensure a system of checks and balances, accountability, and representation of the people's will through their elected representatives in Parliament.
