Unlike former candidate countries where the EU impact has been limited but significant, the article finds a differentiated pattern of Europeanisation in Turkey where the EU plays an indirect role and domestic party politics a causal role in institutional change in regional policy. In this pattern, the EU is a passive provider of institutional templates, which domestic actors in power chose to emulate.eninfo:eu-repo/semantics/closedAccessEuropeanisationinstitutional changeregional policyTurkeyEuropeanizationEuPoliticsEuropeGovernanceRightsArticle10.1332/030557310X5196692-s2.0-79961214185
