Danish Prime Minister Mette Frederiksen has apologised to parliament and mink breeders for ordering the cull of the country's farmed mink population without a full legal basis for doing so.
The government last week ordered the cull of the between 15 million and 17 million animals after health authorities reported the discovery of mutated coronavirus transmitted from minks to humans.
The government has since admitted that, under current law, it lacked the powers to order a cull of healthy minks.
Furthermore, the government only had the power to recommend such a move for farms outside a 7.8-kilometre zone from an infected farm.
Parliament has been asked to fast-track new legislation to also include farms outside the zone.
"Even though it's been hectic, it goes without saying that it must be completely clear when new legislation is required that has not been the case, and I would like to apologise," Frederiksen said.
The apology was also to the mink breeders, Frederiksen said, adding that she was willing to take part in a parliamentary probe into what went wrong.
Members of the opposition, including Jakob Ellemann-Jensen, leader of the Liberals, criticised the government's actions.
Some MPs called for the resignation of Mogens Jensen, the food and fisheries minister, who has admitted he was unaware of the gaps in the law when he addressed media.
According to the prime minister, her office become aware of this at the weekend, after several press conferences.
At least 214 people have since June been infected with variants of the coronavirus.
Concerns were mainly linked to one of the five mink-related variants, the so-called cluster 5, which was found to weaken the ability to form antibodies and could make future vaccines ineffective.
