Marius Borg Hoiby, the 29-year-old stepson of Norway's Crown Princess Mette-Marit, has been found guilty of two counts of rape and given four years in prison after a seven-week trial that has further dented the royal family's once picture-perfect image.

Marius Borg Hoiby has been sentenced in the high-profile scandal that has rocked the monarchy.

A Norstat survey out on February 21 - during the trial - showed a fall in the number of Norwegians favouring keeping the monarchy to a record low of 60%, from 70% in January.
