In parliamentary systems, the **opposition** plays a crucial role by holding the ruling party accountable and ensuring a check on governmental power. They provide alternative policies and critique the government's decisions, fostering healthy debate and facilitating transparency. The opposition often represents diverse views, contributing to political pluralism. During debates, they can challenge proposed legislation and mobilize public support for their alternatives, which can be pivotal in shaping policy outcomes. In some cases, effective opposition can lead to coalitions or changes in government, reflecting the dynamic nature of parliamentary democracy.
