In a speech party secretary Björn Söder likened the Sweden Democrat vision of a perfect society to a scene in an Astrid Lindgren children's book, something which angered her family.
"It was perfectly clear to my mum never to turn away any child that came to Sweden", Lindgren's daughter told tabloid Expressen.
Close friend and biographer Margareta Strömstedt added, "This is completely against everything Astrid Lindgren stood for. She would have been one of the leading figures in the fight against the Sweden Democrats", Strömstedt claimed. Lindgren died in 2002.
