This report is a comparative study of gender equality interventions across Commonwealth legislatures, examining the use of reserved seats, legislated candidate quotas and voluntary party quotas as strategies to increase women’s representation. Drawing on academic research, international datasets, and interviews with women parliamentarians across multiple regions, it explores where direct interventions have driven progress, where they have had limited effect, and what lessons can guide future reform. It provides both an overview of progress and a critical assessment of where further action is needed to advance women’s representation and influence in political institutions.

The report analyses case studies from countries including Rwanda, Uganda, Pakistan, Guyana, Australia and the UK, highlighting diverse pathways to quota adoption and implementation. It identifies enabling factors such as political will, civil society advocacy and constitutional reform, as well as common obstacles including weak enforcement mechanisms, tokenistic approaches, and the risk of reinforcing existing hierarchies when measures benefit only a narrow group of women. While positive action measures have often increased the numerical presence of women, the report shows that substantive impact depends on culture, institutional design and ongoing support beyond legislation alone.

The scope of this report spans Commonwealth legislatures with established and emerging quota frameworks, focusing on the structures and political conditions that shape their success. It does not evaluate party-level mechanisms beyond quota design or provide country-by-country policy prescriptions, but instead offers frameworks, lessons learned and key questions for policymakers, parliaments and advocates seeking to introduce or strengthen gender equality measures. It positions positive action as an important — but not sufficient — tool within a broader system of reform that must address culture, access, safety, resourcing and sustainability to achieve long-term gender parity in politics.
