The chapter uses Twitter data to investigate the extent to which British, Italian, and Spanish journalists employ Twitter to comment on the news as well as reporting on national and European topics, and, conversely, the degree to which the audiences these journalists manage to attract on Twitter reflect the journalists’ or their media outlets’ political affiliations. Our findings suggest that national contexts matter, as journalists working in media environments characterised by lower degrees of parallelism are less likely to use Twitter to provide commentary on the news than those working in outlets or systems where parallelism is higher. We also show that both journalists and news outlets are less likely to editorialise when they tweet about the EU than when they focus on domestic politics.
