The white paper now published shows a clear National Socialist heritage with anti-Semitic expressions and racist ideological ideas among the Sweden Democrats' founders.
There was denial of the Holocaust, immigrants were portrayed as a threat and political opponents as traitors.
My party was founded in a very bad way by people with despicable opinions, says Mattias Karlsson, who is now a member of the party board.
I get damn angry and disgusted over the ideas that were allowed to occur.
Apologizes to Jews
He wants, like party leader Jimmie Åkesson, who joined the party in 1995, to apologize to everyone, especially Jews, who have been afraid of the party.
With that said, I personally feel no guilt for what is described here. I agree with the description that I and many in the party leadership do not see this as our roots.
He believes that the roots have been cut off, that they are dead, but there is a heritage that cannot be influenced.
We will continue to handle this heritage and it is something that we need to take responsibility for in different ways, and maintain the course we have set out: a complete zero tolerance for anti-democratic opinions, fascism, racism.
Mattias Karlsson, who has been described as the party's chief ideologist, joined the SD in 1999 but had come into contact with the party and ordered material as early as 1994.
He says that they were then in a process of change towards becoming a culturally nationalist conservative popular movement.
I felt that it was a work and a process that I wanted to be a part of, he says.
"Did not have the picture clear"
How did you then view the expressions that some representatives had?
I did not have the whole picture clear to me, one is not so politically aware when entering politics and I was relatively young, but I knew about the accusations that they occurred, but I also took part in denials from high-ranking representatives that they existed at all.
The author of the white paper Tony Gustafsson shows, however, that representatives with a National Socialist background occurred in the party into the 2000s.
But for me, it was important that they sent out very clear signals with these exclusion processes that began in the second half of the 1990s and that they had a different rhetoric, a different appearance, and seemed seriously willing to become something else – which they also did, says Mattias Karlsson.
