This Brief examines the impact of Covid-19 on systems of government, emergency response and opposition members in legislatures and their ability to maintain democratic principles. Drawing on insights from five countries as case studies, Malaysia, New Zealand, Papua New Guinea, the Republic of Korea and Singapore, this Brief finds that emergency responses that restrict the capacity of the legislature erode the ability of opposition members to contribute. It also highlights that the role oppositions played during the pandemic varied based on the form of government—be it presidential or parliamentary.
