Replication Data for: What kind of opposition do citizens want?

Opposition parties play a crucial role in democracies. While scholars have extensively studied opposition behaviour and institutional powers, little is known about what citizens expect from opposition parties and how they evaluate these expectations being met. This study addresses this gap by examining citizens' views on three key opposition roles - oversight, cooperation, and offering alternatives - and their perceived fulfilment across four countries: Canada, Denmark, the Netherlands, and the United Kingdom. Based on a citizen survey, this study assesses how individual characteristics (democratic satisfaction, political interest, education) and institutional context are related to these views. Citizens across all four countries value cooperation. Preferences for the ‘alternative’ role vary between institutional settings. On the individual level, conflict-oriented and dissatisfied citizens value cooperation less, while those with higher education and political interest find oversight and cooperation more important.
