The parliamentary form of government ensures that the executive branch, typically headed by the Prime Minister, is derived from the legislature and remains accountable to it. This means that the government can be held responsible for its actions and policies through votes of confidence, enabling a dynamic check on its power. Consequently, this accountability fosters greater cooperation between the executive and legislative branches, promoting a responsive and flexible governance structure that aligns more closely with the will of the electorate. This principle is vital for understanding democratic accountability and institutional balance in governance, which are crucial concepts in UPSC Prelims examinations.
