ABSTRACT
The activities of radicals in a social movement can undermine the position of moderates by discrediting movement activities and goals, and by threatening the ability of moderates to take advantage of the resources available from supportive third parties. Recognizing that social movements are very rarely homogeneous, but consisting of factions and flanks, some scholars have studied intra-movement relations in terms of ‘radical flank effects’. The Sweden Democrats have evolved from a movement party firmly rooted in its neo-Nazi movement origins to a party with significant electoral appeal. This evolution has followed with organizational developments that have successfully distanced the party from its movement roots. The Sweden Democrats have undergone many of the internal organizational strategies which are characteristic of movement parties during a process of reform. However, the neo-Nazi ultra nationalist movement is not only its flora of parties, but also includes a militant revolutionary flank with a violent extra parliamentary agenda.
