This article introduces the concept of centre-periphery dynamics, emphasising the multifaceted distribution of political power and resources between central and peripheral areas within a polity. The study examines how these dynamics influence party-political dissent in Swedish local governments. Drawing on data from a comprehensive survey of councillors across Sweden's 290 municipalities, it analyses whether political dissent vary across policy areas such as taxation, refugee reception, and public service locations. The findings indicate that while centre-periphery dynamics does not influence conflict levels in most areas, they significantly affect dissent regarding location of public services. Conflicts are more likely to escalate in municipalities with a larger portion of the population residing outside the administrative centre and spread across a wider area. These results suggest that centre-periphery dynamics play a crucial role in shaping party dissent, particularly on issues relevant to territorial politics, and that the level of dissent primarily depends on the capacity of disadvantaged groups to mobilise and advocate for their interests.
