OSLO (Reuters) -The son of Norway's crown princess has been charged with rape, domestic violence, assault and other crimes following a year-long police investigation, a prosecutor said on Monday. Marius Borg Hoiby, 28, son of Crown Princess Mette-Marit and stepson to Crown Prince Haakon, is expected to stand trial early next year and could face up to 10 years in prison if found guilty of the most serious charges, the prosecutor said. "He does not agree with the claims regarding rape and domestic violence," Sekulic said of his client.
