Question Hour and Zero Hour

Question Hour and Zero Hour are important parliamentary procedures. They allow Members of Parliament (MPs) to oversee government functions. These sessions help MPs hold Ministers accountable and raise urgent issues affecting their constituents. Understanding these interventions is key to competitive exams focusing on Indian Polity.

Question Hour and Zero Hour in Parliament

The Indian Parliament uses various methods to ensure government accountability. Among these, Question Hour and Zero Hour stand out. They provide direct opportunities for MPs to scrutinise policies and actions.

Question Hour

Question Hour is the first hour of every parliamentary sitting. It starts daily at 11:00 AM. During this time, Members of Parliament (MPs) can ask questions to Ministers. This process holds the government accountable for its policies. Ministers must answer these questions. MPs can seek details on policy implementation or issues impacting their constituents.
