A member of a European royal family has been sentenced to prison after being found guilty of rape and other serious offences in a case that has drawn intense scrutiny in Norway and beyond.

Marius Borg Høiby, the 29-year-old son of Norway’s Crown Princess Mette-Marit, was sentenced to four years in prison after a court in Oslo found him guilty of multiple charges, including two counts of rape, according to reports cited by local media.

The verdict was delivered by the Oslo District Court following a trial that has unfolded over several months. Høiby was not present in the courtroom at the time of sentencing, instead participating via video link, according to reports.

Prosecutors said the case involved multiple serious allegations, though the court acquitted him on some additional counts brought during the proceedings. The sentencing marks one of the most high-profile criminal convictions involving a person closely connected to a European royal household in recent years.

Høiby is the eldest son of Crown Princess Mette-Marit, who married Crown Prince Haakon in 2001, formally joining Norway’s royal family. Despite his family connection, he does not hold any royal title, succession rights, or official public role.

The case has unfolded under intense media attention in Norway, reflecting broader public scrutiny of figures connected to royal institutions even when they do not hold formal positions.

According to reports, the court found him guilty of two rape charges and issued a four-year prison sentence, while clearing him of other allegations. The judgment was delivered by a panel of judges at Oslo District Court.

The conviction closes a legal process that has raised difficult questions in Norway about accountability, public scrutiny, and the boundaries between private conduct and proximity to the royal family.

Royal officials have not issued detailed public comment on the verdict, and the Crown Prince couple have previously said they would allow the legal process to proceed without interference.

For Norway’s monarchy — one of Europe’s quieter royal institutions — the case represents an unusual moment in which the private life of a royal household member has collided directly with the criminal justice system.
