When SSV approved the 21 thesis of the ComIntern and thus changing name to SKP (Communist Party of Sweden) in 1921, an anti-ComIntern minority were expelled and founded their own "SSV". This "SSV" existed between 1921 and 1923. The leader of this party was Ivar Vennerström. "SSV" participated in two  elections, the parliamentary elections of 1921 (gaining 3,2%) and the municipal election in 1922 (gaining 1,8%). In 1923 they were reunified with the social democrats.

Västerbottens Folkblad, a newspaper published in Umeå was then a publication of this tendency. Today it's a social democratic newspaper. There's a page about it made by the Royal Library.
