The son of the Norwegian Crown Princess has been sentenced to jail for four years after being found guilty of rape.

Marius Borg Høiby, 29, is the eldest child of Mette‑Marit, Crown Princess of Norway.


He became the stepson of Crown Prince Haakon when his mother married the future king in 2001.

Although he has appeared with the Norwegian Royal Family on several occasions, he holds no royal titles, succession rights, or official public duties.

Borg Høiby was found guilty of two counts of rape and sentenced to four years in prison on June 15.

The three judges in courtroom 250 at Oslo District Court acquitted him of two other counts of rape.

The Norwegian royal had been facing 40 charges during his trial.

Borg Høiby was found guilty of many of the other offences of which he had been accused, including domestic abuse against an ex-girlfriend, issuing threats and traffic violations.

The 29-year-old was not in court for the verdict, but joined the session via video link.

Prosecutors had called for Borg Høiby to be given seven years and seven months in prison.

His defence lawyers had called for a lesser term of 18 months and can appeal against the verdict.

The seven-week trial gripped the Scandinavian country, detailing Borg Høiby’s drug addiction, self-made videos of sexual encounters and more than 800 electronic messages entered into evidence.

Borg Høiby denied wrongdoing and has the option to appeal today’s verdict.

The Norwegian royal had been in police custody since the start of February.

Local police had detained him shortly before the trial began, on suspicion of assault and violating a restraining order involving an ex-girlfriend.

The verdict was delivered amid difficult personal circumstances for Mette-Marit, Borg Hoiby's mother.

This month, she was placed on the national lung transplant list as her health severely deteriorated.

The 52-year-old suffers from pulmonary fibrosis, a condition that makes it increasingly difficult to breathe.

Without a transplant, she has around a year left to live, her doctors have said.
