Stepping Stone, Halfway House or Road to Nowhere? Green Support of Minority Government in Sweden, New Zealand and Australia

Whilst much has been written about the opportunities and perils of Green participation in national coalition governments, analysis of Greens supporting minority governments is less common and has not focused on comparative-historical trends as this article does. We look beyond single case studies of Green-supported minority governments in order to establish historical party trajectories and policy impact over time in three countries with different political systems. The extent of the comparative work here has never previously been undertaken and establishes that repeat instances of such support can provide the basis for more stable and effective future interparty governing relationships. However, we argue that, whilst trust can build between parties to minority government arrangements over decades, it is not assured, and, whilst Green parties may achieve ministerial control after repeat instances of supporting minority governments, the benefits of doing so are not guaranteed
