This article explores political discourse in the context of an online-mediated 2021 rapprochement between Swedish 'mainstream' and far-right parties paving the way for their eventual 2022 electoral success and later joint government coalition. The article analyses specifically how the above political accord on the Swedish right - often seen as breaking the long-term cordon sanitaire around Sweden's far right - would be legitimised via discourses that carried significant elaboration and deepening of the 'criminality' and 'immigration' connection later recontextualised into the broader Swedish public discourse and public imagination. Using social media analytics and qualitative, critical discourse analysis, we explore in depth a 'discursive shift' wherein the focus on criminality would become a key 'proxy discourse', i.e., a public-wide implicature, which, while referring to and debating a potentially genuine social issue would be strategically instrumentalised to effectively pre-legitimise 'moral panics' around immigration and cultural diversity. The analysis highlights that the emergence as well as the later recontextualisation of the 'proxy discourse' in question - implicitly suggesting that criminality, immigration, and cultural diversity are 'somehow' inherently connected - not only supported the political mainstreaming of the Swedish far-right's anti-immigration stance but also normalised the wider tenets of illiberal, nativist 'politics of exclusion'.
