The use of social media in order to disseminate political communicational strategies has increased in Sweden. Previous studies have showed that social media can benefit right-wing political parties and other ideologically marginalised parties. The Sweden Democrats (SD) have since long preferred social media over main stream media. This paper presents a multimodal critical discourse analysis of a sample from a larger corpus of multimodal posts and video material about immigrants from the social media pages of right-wing populist part Sweden Democrats (SD). Drawing on Van Leeuwen’s and David Machin’s framework for the representation of social actors, this paper investigate how multimodal resources contribute to shaping immigration discourse and to its bias, highlighting exclusionary ideologies through the decontextualisation of social practices. The result of this study show that SD are using the five communication strategies similar to that used by nativist propaganda to emphasise the view of immigrants as a threat to Swedish society. The othering of immigrants as non-natives is enacted through biased representation based on covert racist stereotypes. At the same time, visual anti-immigration rhetoric allows the leaders to “build their people” and self-promote their role as gate-keepers of the nation-state, and the public is urged to vote for them in order to restore security.
