The Office of the Chancellor of Justice has received two complaints from members of the public over the failure to properly inform Prime Minister Sanna Marin (SDP) that she had been exposed to the coronavirus.

Marin has been at the centre of a media storm after reports emerged that she had been clubbing with friends in central Helsinki on Saturday night and missed two messages cautioning her against close contacts with others.

The Prime Minister had been in a meeting with Foreign Minister Pekka Haavisto (Green) on Friday, just one day before Haavisto tested positive for the virus on Saturday.

One of the complaints relates to the fact that Marin did not have her official government phone with her in the nightclub, and therefore missed the SMS messages sent by the government's Chief of Security advising cabinet members to self-isolate if they had been in the meeting with Haavisto.

The second complaint criticises the failure of the Prime Minister's Office to adequately inform Marin about her exposure to the virus.

Marin left to meet friends in Helsinki city centre despite being informed of Haavisto's confirmed coronavirus infection by her secretary of state at about 7.20pm on Saturday evening.

She subsequently explained to tabloid Iltalehti that she was given instructions that the potential exposure did not require quarantine or any other special measures, as members of the cabinet had received two vaccinations.

"This information is in line with THL's general guidelines for citizens, and therefore I did not question it," Marin said.

The Chancellor of Justice rules on complaints concerning government ministers as well as ministries and other departments, and investigates complaints if they give rise to suspicion of unlawful conduct or failure to fulfill the duties of office.
