The function of an opposition party in a parliamentary system is to provide checks and balances to the ruling government. They serve as a voice for dissenting views and critique governmental policies and decisions, holding the ruling party accountable. Additionally, opposition parties play a vital role in shaping public discourse, offering alternative policies, and mobilizing voters. Their existence ensures a multiparty dialogue, fostering democratic debate and preventing the concentration of power. Consequently, an effective opposition is essential for the health of democracy, promoting transparency and responsiveness within the political system.
