Storting party at the palace: jokes, seriousness, elk and roll cake
King Harald is on sick leave, but Queen Sonja and Crown Prince Regent Haakon are hosting representatives of the Storting on Thursday.
The king fell ill on October 22 and had cold symptoms as a result of the corona. It was later announced that he would remain on leave as long as he was asymptomatic.
Three days later, the royal palace announced that King Harald had fallen ill this week.
Raja contracted the virus for the first time in March last year.
