Explanation: In the Indian political system, the Prime Minister holds a pivotal role as the head of the government and the leader of the Council of Ministers. The Council of Ministers is collectively responsible to the Lok Sabha, the lower house of the Indian Parliament. This principle of collective responsibility means that the Council of Ministers stands or falls together with the Prime Minister.
The Prime Minister is appointed by the President of India, who is the constitutional head of the state. However, the Prime Minister must command the confidence of the Lok Sabha to remain in office. If the Prime Minister resigns, it is a signal that the government no longer has the support of the majority in the Lok Sabha. Consequently, the entire Council of Ministers must resign to maintain the principle of collective responsibility.
This principle ensures that the government operates as a cohesive unit, with all ministers supporting the policies and decisions of the Prime Minister. If the Prime Minister resigns, it implies that the government's policies and decisions are no longer viable, and thus, the entire Council of Ministers must resign to allow for a new government to be formed.
It is important to note that the resignation of the Prime Minister does not automatically lead to the dissolution of the Lok Sabha. The President can invite another leader to form a government if the resignation is due to a loss of majority but not a complete collapse of the government. However, in most cases, the resignation of the Prime Minister leads to a general election to form a new government.
Understanding the role of the Prime Minister and the principle of collective responsibility is crucial for comprehending the dynamics of the Indian political system. This concept is tested in various competitive examinations, including the UPSC Civil Services, State PSC, and CLAT, where candidates are expected to have a thorough understanding of the Indian political framework.
