Using constructivist representation theories, this article presents a framework for understanding how political staff shape representation. Using a survey of 366 parliamentary and constituency staff working for members of Parliament (MPs), I identify four key roles: proxies, liaisons, advisors, and gatekeepers. Proxies embody absent elected officials. Liaisons facilitate communication between elected officials and constituents. Advisors’ expertise and experience shape elected officials’ actions. Gatekeepers manage people’s and ideas’ access to elected officials. Constituency staff primarily act as proxies and liaisons, emphasizing local service and constituent connection. Parliamentary staff more often take on advisory and gatekeeping roles, which can influence elected officials’ perspectives. This framework provides insight into how staff mediate the representative process between elected officials and constituents. Staff actively shape who is heard and which issues gain attention, ultimately influencing the quality and inclusivity of democratic political representation. Thus, understandings of representation without staff are inherently incomplete.
