Prince Sverre Magnus of Norway
The Constitution of Norway was changed in 1990 to introduce full primogeniture, ensuring that the crown would pass to the eldest child regardless of sex but keeping the Crown Prince ahead of his elder sister, Princess Märtha Louise. This change applied for the first time to the children of the Crown Prince, meaning that Sverre Magnus would not rank above his elder sister, as would have happened under the older constitutional rules. Sverre Magnus is third in the line of succession to the Norwegian throne following his sister. He is a member of the Royal Family but not of the Royal House, which includes only his grandparents, parents, and sister.
