Marius Borg Høiby, 29, on trial accused of 38 crimes, broke down in tears as he claimed press had harassed him for years

Marius Borg Høiby, the son of Norway’s crown princess, has told a court he does not remember taking pictures and videos found on his phone that police say show him sexually assaulting a woman at a royal residence.

Høiby, Mette-Marit’s son from a relationship before her marriage to Crown Prince Haakon, is on trial accused of 38 crimes, including four rapes and assaults.

He has pleaded not guilty to the most serious offences, including the alleged rapes, and faces up to 16 years in prison if convicted.

The trial comes at a moment of unprecedented pressure on the Norwegian royal family, with Mette-Marit also facing criticism over her links with the late sex offender Jeffrey Epstein.
