Oslo - Norway's Princess Mette-Marit has taken up a course in "meaningful leadership and power" at an Oslo business college, the royal court confirmed Thursday.

The institute's director Tom Colbjornsen said the course would be relevant to company culture and also to state leadership past and present.

Mette-Marit, 35, had enrolled for a three-year, part-time course along with 50 fellow students.

She and Prince Haakon have two children - Princess Ingrid Alexandra, 4, and Prince Sverre Magnus, 2 - plus Mette-Marit's 11- year-old son Marius Borg Hojby from an earlier relationship. (dpa)
