Do researchers that use ethnographic methods study parliaments and parliamentary actors in the same way? While parliamentary ethnography is a growing research methodology to study political phenomena, such as informality, political behaviour and interpretations of parliamentary work, less is said about how access to sites and actors may affect analytical foci, strategies and outcomes. This neglects the complexity of parliamentary organisation and distinctive practices of parliamentary actors. We draw attention to this complexity to investigate how different levels and types of access to parliaments, and actors therein, affect ethnographic research. We reflect on this issue through four themes: (1) entry and access, (2) adapting to organisational rhythms, (3) ethnographic capital of researchers and (4) analysis and publication of findings. We argue that there is no ‘right’ or ‘wrong’ way of undertaking ethnographies of parliaments, but emphasise that researchers must explicitly reflect on how their particular strategies may shape ethnographic research on parliaments.
