How transnational are the audiences of far right parties and movements on Twitter? While an increasing number of contributions addresses the topic of transnationalism in far right politics, few systematic investigations exist on the actors and discourses favored in transnational exchanges on social media. Building on the literature on the far right, social movements, transnationalism and the Internet, the paper addresses this gap by studying the initiators and the issues that are favored in online exchanges between audiences of far right organizations, e.g. political parties and movements across France, Germany, Italy and the United Kingdom. We use a new dataset on the activities of far right Twitter users that is analyzed through a mixed methods approach. Using social network analysis, we detect transnational links between far right organizations across countries based on retweets from audiences of far right Twitter users. Retweets are qualitatively coded for content and compared to the content retweeted within national communities. Finally, using a logistic regression, we quantify the level to which specific issues and organizations enjoy high levels of attention across borders. Subsequently, we use discourse analysis to qualitatively reconstruct the interpretative frames accompanying these patterns. We find that although social media are often ascribed much power in favoring transnational exchanges between far right organizations, there is little evidence of this. Only a few issues (anti-immigration and nativist interpretations of the economy) garner transnational far right audiences on Twitter. In addition, we find that more than movements, political parties play a prominent role in the construction of a transnational far right discourse.
