Between Core and Peripheral Politics: Opposing the EU in the Western Balkans

This article seeks to determine whether parties’ governmental/opposition and core/peripheral positions in the Serbian and Croatian party systems are related to their responses to European integration. In general, parties’ positions in the party system were not crucial driving forces behind their stances towards the EU. However, the experience of opposition significantly contributed to ideological transformation and the adoption of a Euro-enthusiastic agenda by strategically motivated, formerly Eurosceptic parties. Also, different types of party systems in Serbia and Croatia created different opportunities for parties to express Eurosceptic sentiments, with a fragmented and polarised system in Serbia being more conducive to the sharp contestation of EU issues.
