The Princess of Norway's former husband has claimed Kevin Spacey groped him when they met during a Nobel Peace Prize party ten years ago.

Ari Behn, who was married to Norway's Princess Martha Louise until last year, claims he was propositioned by the disgraced actor.

The House of Cards star met with the then-royal while he was hosting the Nobel Peace Prize concert in Oslo along with Uma Thurman.

"We had a nice conversation, he was sat next to me," Mr Behn, told Norwegian radio station P4.

"After five minutes, he says 'Hey, let's go out and have a cigarette', and then he touched me right on the balls under the table."

Behn said he was so put out all he could say was "eh, maybe later".
