Political group formation in the European Parliament (EP) after European elections is a core feature of supranational party politics. The research objective of this article is to scrutinise democratic practices and the role of values, more specifically gender equality, in this political group formation. Complementing extant literature, this article engages with gendered political group formation as a dynamic process consisting of three intertwined layers, which are assessed by analysing formal and informal institutions around democracy and gender. The article draws on a unique data set of 130 interviews with MEPs, political group and parliamentary staff conducted in 2018–2020. The key findings of the article show that gender plays a role in each layer of political group formation, yet there are clear differences between political groups. By deciphering the reasons behind these differences, the article enhances the understanding of the political dynamics and struggles within the political groups.
