The Irish party system has been exceptional both for the weakness of its left-right conflict and for its long-run stability. How then can party competition on policy, and particularly competition between the main parties, be characterised? This study examines the Irish party system from an issue competition perspective, examining the party system agenda and asking whether Irish party competition is marked by differences in issue focus. New data from Irish party manifestos (1981-2020) coded within the framework of the Comparative Agendas Project show that rather than competing by focusing on different issues, Fianna Fail and Fine Gael's issue focus is very similar and has moved in parallel over time. Nor is a distinct focus on new issues evident in Sinn Fein's offering as they have emerged as a major party. Moreover, it finds that 'new politics' issues have remained marginal and it examines how this has occurred using the 'crucial case' of environmental policy. While differences in issue focus do not help us to distinguish the main parties, the politics of competence continues to have an important role and positional politics may be coming to the fore.
