dc.description.abstractResearch on voting behavior in the European Parliament (EP) has long shown that legislative alignments are structured by multiple ideological dimensions whose salience varies across policy areas and political contexts. Building on this literature, this study maps coalition structures in the EP’s 9th term (2019–2024) using a co-voting network backbone approach applied to roll-call vote data. By extracting statistically significant co-support relationships among Members of the European Parliament (MEPs), we identify how coalition configurations realign across major policy areas and cannot be reduced to a single left–right divide. The results reveal pronounced issue-dependent coalition patterns: larger and governing groups, including EPP and S&D, exhibit fragmented coalition behavior, aligning with different partners depending on the policy domain. Votes on the institutional development of the Union highlight a pro- and anti-European integration dimension that cuts across traditional ideological alignments without fully replacing them. Despite facing unprecedented challenges—including Brexit, the COVID-19 pandemic, Russia’s war against Ukraine, and a period of record inflation—the EP maintained its transnational character: ideological affinity and party group membership, rather than nationality, remain the primary drivers of voting alignment. Rather than revising established accounts of the EP’s ideological space, this study contributes a complementary network-based perspective that makes coalition cohesion, fragmentation, and cross-group alignment structurally and visually explicit.en
