Regionalist parties were born to politicize the centre-periphery cleavage at the level of the state. However, the dynamics of party competition have pushed state-wide parties to adopt positions on territorial issues and induced regionalist parties to diversify their ideology by including other dimensions of contestation. Consequently, regionalist parties have strategically adopted positions along the left-right dimension and on other issues. Amongst them, of particular relevance is the question of European integration. This paper investigates the linkage between, on the one hand, regionalist parties’ positioning on self-government and on the left- right dimension within the state, and, on the other hand, their positioning on European integration. The extant literature disagrees on the exact positions of these parties towards European integration. Using recent datasets the paper traces differences in the level of support for European integration in order to explore different patterns of positioning, with specific focus on linkage between ideological dimensions.
