Convictions of political corruption depend on public communication, since for citizens, to perceive deviant behaviours, these must receive attention. In Spain, this type of behaviour is part of the agendas of citizens, media, and politicians and, to fight against it, accountability is essential. In addition to the judiciary and legislature (in their oversight role), the media and social media help voters, MPs and others to make informed decisions and press for action. However, the interrelationships between different agents, types, and forms of control for accountability are a rather unexplored research topic, especially when considering non-accountable institutions (those that have power, but are not directly accountable to the electorate, such as the monarchy). The debate on the inviolability of the emeritus presents a perfect scenario to describe what formulas and what kind of sanctions (legal, labour, reputational or personal) for accountability have occurred in Spain in the case of a non-accountable institution. This study explores the agendas of media, Parliament, and Twitter (and their inter-influences) during the Geneva papers scandal. We analyzed 189,037 tweets, 1,220 journalistic pieces and 78 parliamentary initiatives related to the former monarch. The main results show that the media, social networks, and Parliament have acted as agents of accountability with Juan Carlos I, as if it were an accountable institution. Online newspapers and Twitter have led the oversight, while the parliamentary initiative has been ineffective and has essentially served as an instrument of partisan communication.
