This study examines how conceptions of sovereignty have been constructed and framed in relation to Sweden's EU membership through a qualitative analysis of three parliamentary debates from 1994, 2008, and 2023. By examining the debates, surrounding fundamental developments in Sweden's EU relationship, the research sheds light on the evolving political discourse on sovereignty. Employing a framing analysis, the study focuses on three key dimensions of sovereignty: national, supranational, and shared. The findings reveal shifting framings that illustrate a tension between traditional Westphalian notions of sovereignty, emphasizing state autonomy and control, and more dynamic interpretations that embrace elements of European integration. While critics of EU integration often emphasized threats to national sovereignty, advocates tended to frame shared sovereignty as a means to strengthen Sweden's influence in handling transnational challenges. The analysis further highlights the difficulty in categorizing statements into distinct notions of sovereignty, as many framings mix elements of national, shared, and supranational sovereignty. This demonstrates the nuanced and sometimes contradictory positions within Swedish political discourse, reflecting a broader struggle to reconcile national autonomy with the demands of regional collaboration and global interdependence. By examining these debates, the study demonstrates how Swedish political actors navigate the interplay of national autonomy, democratic legitimacy, and regional collaboration, providing insights into broader debates on sovereignty in a globalized context.
