She’s in line to be Queen of Norway one day, but Princess Ingrid Alexandra has to take a lower place in another line of succession thanks to different rules. She is one step behind her younger brother, Prince Sverre Magnus, in the line to the British throne.

Ingrid Alexandra is second in line to Norway’s crown. Her father, Crown Prince Haakon, is first in line and she is directly behind him. When he becomes King of Norway, she will become heir and will, in due course, succeed him to reign as queen.

Princess Ingrid Alexandra was born in January 2004 and, thanks to a change to succession rules in the late 20^th century, she couldn’t be overtaken by any younger brothers. When her parents, Crown Prince Haakon and Crown Princess Mette-Marit, welcomed a son, Sverre Magnus, on December 3^rd 2005, he was third in line, behind his sister.

However, he took a different place in the British line of succession. Norway’s current royal family is directly descended from King Edward VII and Queen Alexandra. Their youngest daughter, Maud, became Queen of Norway in 1905. Five years later, Edward and Alexandra’s only surviving son became King George V on the death of his father.

George V’s great grandson now reigns as King Charles III. Queen Maud’s grandson, Harald, is the current King of Norway. And so the Norwegian Royal Family are also in the line of succession to the British throne, albeit a long way down.

When Ingrid and Sverre were born, the British rules around succession were still governed by absolute primogeniture. Until 2012, boys automatically overtook their elder sisters. And so, Sverre Magnus leapfrogged Ingrid Alexandra in the line to the British throne.

When the rules were changed in the UK, with succession determined by birth order not gender, they weren’t made retroactive. Anyone born before 2012 stayed where they were. And so Prince Sverre Magnus, who turned 18 on December 3^rd 2023, remains one step ahead of his sister in the British succession even though she will, one day, reign in Norway.
