Research on representational roles has been set so far in the context of the national state, with variations between the formal national institutions of these states explaining the variations in these roles and the possible ‘agency loss’. In this project we want to conceptualize principal-agent relations explicitly in a context where the control over policy making has been in varying and non-symmetrical ways pooled at the European level and devolved to regions. That also means that policy making, participation and delegation chains vary between sectors and between territories. We analyze representational roles of office holders and party strategies in multi-layered systems. We draw upon a comparative survey of MPs.
