In an opinion piece for the local Hallandsposten newspaper, Jerzy Golowkin, a Moderate Party politician in Halland county, described Reinfeldt's recent comments that he would rather leave office than work with the Sweden Democrats as "frightening" and "undemocratic".
Golowkin co-wrote the opinion piece with two Sweden Democrat politicians, Oleg Datsishin and Georg Cserti.
Reinfeldt made the comments during the recent political festival, Almedalen. He heads the Moderate Party, the largest of the four parties in Sweden's centre-right coalition.
Michael Svensson, chairman of the Moderates' party association in Halland, told Hallandsposten that he feels the article and Golowkin's choice of co-authors is problematic.
Svensson said the Moderates should not be linked to "the Sweden Democrats' hate" and that the Moderates do not want to attract people who vote for the anti-immigration party.
