Marius Borg Høiby, the 29-year-old son of Norway's Crown Princess Mette-Marit, has been sentenced to four years in prison after being found guilty of two counts of rape.

Høiby faced four rape charges in total but was convicted on two counts while being acquitted of the other two charges. The court proceedings concluded with the four-year prison sentence.

Høiby is the stepson of Crown Prince Haakon, having become part of the Norwegian royal family through his mother's marriage to the crown prince. Crown Princess Mette-Marit had Høiby from a previous relationship before her marriage into the royal family.

The case represents a significant legal matter involving a member of Norway's royal household, though Høiby does not hold an official royal title or position in the line of succession to the Norwegian throne.
