This article investigates whether agenda-setting relations between newspapers and political parties are influenced by political parallelism. Our case is the Netherlands, a country characterized by high levels of journalistic professionalization and independent media. We focus on newspaper coverage and oral parliamentary questions and use time series analysis to inspect influence both of parliament on newspapers and of newspapers on parliament. The results show that parties respond only to issues raised in newspapers their voters read, and that newspapers only respond to the agenda of parties their readers vote for. This demonstrates that even in mediatized, professionalized media contexts, parallelism is still of importance to understand the relationship between media and politics.Keywords political parallelism, agenda-setting, parliamentary questions, newspapers, the Netherlands
IntroductionIn recent years, the political agenda-setting approach toward studying the interaction between parliament and media has become increasingly popular. Extant research in this tradition shows that the effect of media on politics and vice versa is a contingent one, where direction and size depend on a wide variety of factors. These factors cover a whole range of issue characteristics, media characteristics and political party characteristics (see Walgrave & Van Aelst, 2006 for an overview). Until recently, however, maybe one of the most obvious moderating factors has received hardly any attention: political parallelism. Political parallelism refers to the ties between a medium and a political actor (Hardy, 2008;Seymour-Ure, 1974). It is quite remarkable that political parallelism has been ignored as a moderating factor, since Hallin and Mancini identify it in their seminal work Comparing Media Systems (2004) as one of the most important elements that characterize the media system of a country.Daphne J. van der Pas is Postdoctoral Researcher, and Wouter van der Brug is Professor, Department of Political Science, University of Amsterdam.

491As far as we are aware, there is only one study that focuses on the extent to which political parallelism moderates agenda-setting effects: a study by Vliegenthart and Mena Montes (2014) on the coverage of the economic crisis. They show that in Spain, a country with high levels of political parallelism, political agenda-setting effects are particular...
