Elisabeth Peterson, who is second on the partys candidate list for the municipal council in the city of Växjö, laughed when confronted by the newspaper about sharing the song this February.
The song is by Kiwi, who has collaborated with the white power record label Midgård records, and played his music on the far-right website Nordfront.se.
When asked about what constituted a “Swede”, Peterson excluded any recent immigrants to the country.
“You should be Swedish, born Swedish and have Swedish parents,” she said.
The Sweden Democrats leader Jimmie Åkesson has repeatedly claimed that his partys nationalism is not ethnocentric, and that even people born abroad can be Swedish if they fully adopt the national culture.
“Swedishness is open, you should be able to become Swedish even if you werent born in the nation of Sweden,” he said on Swedish Radio last week, although he added that it can take a long time, perhaps generations, before this happens.
As well as compaigning for election, Peterson is secretary of the partys board in Växjö and its spokesperson on education.
Henrik Gustafsson, from the partys press department, said that the party planned to investigate Peterson.
“We have grounds to investigate this issue according to our working practices and internal routines,” he said. “Our membership committee is going to take this issue further.”
The partys local chairman, Tobias Lindgren, distanced himself from Peterssons actions.
”This is unacceptable and in no way corresponds to the partys views about open Swedishness, the priciple of assimilation, or that we believe, are working for, and hope that people who come to Sweden can also become part of the society,” he said.
