As several studies have reported on legislative behavior in previous European Parliament terms, this thesis aims to capture the effects of electoral systems, parliamentary groups’ ideological orientation, and policy salience on legislative behavior of Members of the European Parliament during its ninth term (2019-2024). This thesis relies on a range of theories, from rational choice institutionalism to concepts of ideologies and policy salience, alongside previous studies, to generate testable hypotheses. Conducting a statistical analysis of voting records, the research contributes to the academic discourse on how institutional and ideological parameters shape European party groups’ cohesion in the aftermath of the 2019 European Parliament elections. The thematic analysis suggests that certain aspects of parliamentarians’ defection from their party group majority votes can primarily be affected by ideological groupings and policy areas rather than institutional electoral parameters.
