In clips, recorded with a hidden camera, KD's party secretary Peter Kullgren and deputy party secretary and chief financial officer Robert Lisborg suggest procedures for receiving large anonymous contributions to the party from a businessman under a false flag.

This is revealed by TV4's social program Kalla fakta.

The approaches presented circumvent the law on transparency in parties' financing, which states that parties must report private contributions over SEK 24,150.

KD leader Ebba Busch, on the other hand, believes that her party colleagues have acted according to the rule book, she says when she meets the press before Aftonbladet's party leader debate on Wednesday evening.

- I understand that they have tried to start from the existing regulations and legislation, says Busch to TV4.

- An arrangement was discussed that my employees made the assessment would not have been compatible with the regulations and then we would not have been able to proceed with this donor either, she says to SVT Nyheter.
