Dr Arno van der Zwet was one of the co-editors and contributors of a recently published special issue on immigration attitudes in sub-state nationalist and regional parties .
The introductory article of the special issue examines how sub-state nationalists respond to the growing presence of cultural diversity in their 'homelands' resulting from migration. Migration to the 'homeland' of a sub-state nation presents a conundrum for sub-state elites that is labelled the 'legitimation paradox': too much internal diversity may undermine the claim to cultural distinctiveness. Arno's second contribution focuses on how different conceptions of national identity can be linked to attitudes towards cultural pluralism. Empirically, the article examines these issues in the case of the Scottish National Party and Frisian National Party in the Netherlands.
