Finnish Prime Minister Sanna Marin said on Friday she had taken a drugs test following the publication of video footage this week that showed her partying with friends, and vowed she had never used illegal drugs.

Marin, 36, also said her ability to perform her official duties had remained unimpaired on the Saturday night in question and that she would have left the party had she been required to work.

Video clips of Marin partying with well-known Finnish influencers and artists began circulating in social media this week and they were soon published by several media outlets in Finland and abroad.

“In recent days, there have been quite grave public accusations that I was in a space where drugs were used, or that I myself used drugs,” Marin told a news conference.

“I consider these accusations to be very serious and, though I consider the demand for a drug test unjust, for my own legal protection and to clear up any doubts, I have taken a drug test today, the results of which will come in about a week.”

Marin, who became the world’s youngest serving government leader in December 2019, had faced calls from members of her governing coalition as well as from the opposition to take a drug test after the videos emerged.

Social Democrat leader Marin said she had never taken drugs and that she had not seen anyone doing so at the party she attended.

While many have praised Marin for combining her demanding job with an active private life, others have questioned her decision to allow herself to be filmed even when promised that the videos would not be made public.

At a time when Europe has been unsettled by Russia’s war in Ukraine, Marin has also faced criticism that her partying could interfere with her ability to quickly carry out her duties if a sudden crisis hit Finland.

“If there were to be a crisis situation, I would know about it before midnight on a Saturday evening,” she told reporters, adding that the Finnish armed forces were well equipped to anticipate any military crisis that might affect the country.

Finland, which shares a long land border with Russia, has applied along with neighbouring Sweden to join NATO following the war in Ukraine.

The clips were originally posted to a private Instagram account.

“These videos are private and filmed in a private space. I resent that these became known to the public,” Marin told reporters on Thursday.

She said she did not know who leaked them.

Newspaper Helsingin Sanomat said the episode raised questions about her judgment.“Marin may have acted in good faith, but this gullible she should not be,” the paper wrote in an editorial.

“The prime minister can, in a sensitive situation, put the weapons of information warfare in the hands of those who would like to hurt Finland,” the newspaper said.

Marin said the video was a compilation of clips from two separate occasions a few weeks ago. She said people at the events consumed alcohol but no one took drugs to her knowledge.

“We just partied, also in a boisterous way. I danced and sang,” Marin said, denying a claim that the videos had been a publicity stunt less than a year until the next general election.

Marin in January told Reuters she and her fellow young female ministers have been targeted with extensive hate speech for their gender and appearance while in office.
