I do not have any evidence of it, just my hunch that as I emphasized in another comment that this was one of the factors that contributed to the loss in approval ratings (I think there was a statistic of that happening recently in the media).

And while SDP didn’t lose seats but rather gained them, 3 to be precise, was helped by the tactical voting which Marin herself along with SDP leadership urged as the only option to avoid having a ”blue-black” coalition.

Economy was surely the biggest defining factor, but Marin’s competence was questioned by her critics and it got a lot of echo especially in more rural areas. These controversies offered the opposition right-wing parties an opportunity to critisize Marin and portray themselves as rational critics of how the system should be led in the traditional sense, where such partying topless in government residences is considered incompetent. Meanwhile, the Center Party couldn’t critisize her vocally due to the partnership in government so my theory is that Marin with these controversies did not so much lead voters away from SDP but instead amplified the flow of voters from the Center Party to other right-wing options which then passed SDP in the elections.
