In this article, we analyze transnational party politics in the European Union from a gender perspective. This is a subject that has been neglected both by mainstream European studies on party politics and by gender scholars who work on political parties. Drawing on the insights of these two research traditions, we build toward an analytical framework to study gender and transnational party politics. Our empirical analysis focuses on two policy issues, the economic crisis and the sexual and reproductive health and rights, analyzing European Parliament reports, debates and voting on the issues from 2009 to 2014. By focusing on gender equality constructions and the way in which consensus and contestation are built around them within and between party groups, we argue that shared constructions about gender equality are issue specific and change over time. Consensus breaks down along the left right axis and, at the same time, internal divisions within party groups affect policy output.
