The royal palace on Thursday confirmed the couple’s intentions to leave Norway. The three girls, Maud Angelica, who turns nine on Sunday, Leah Isidora (7) and Emma Tallulah (3), are to be enrolled in an English school, newspaper VG reports.
Despite the proposed change of scene, the princess – who also claims to be able to talk with angels – will continue to run her own English-language school in Norway, Astate Education.
The palace could not give an exact date for the move and said it did know how long the royal family intended to stay in the British capital.
“Princess Märtha Louise will continue to have her official duties, for which she will commute,” palace spokeswoman Marianne Hagen told news agency NTB.
The princess will also continue her work with people with disabilities, Hagen added.
“And it’s therefore very appropriate that the Paralympics will be held in London.”
The 40-year-old princess married the author Ari Behn, 39, in 2002.
That same year she renounced the title Her Royal Highness, preferring instead to focus on her activities as an independent businesswoman.
The princess and Ari Behn have lived in Lommedalen, south-eastern Norway, since 2003.
Earlier this year, Princess Märtha Louise saw her second book about angels storm to the top of Norwegian bestsellers’ lists.
The princess, who also has an alternative medicine business, wrote the book with fellow author Elisabeth Nordeng.
"There are an infinite number of angels all around us who want to help us in all circumstances and at all times," the princess and Nordeng wrote in their introduction to the book "the Secrets of Angels".
"They are there for us. They are real. They exist," they added.
