Norwegian princess investigated over role in commemorative wedding gin

Märtha Louise is not allowed to use her title commercially after renouncing her royal duties two years ago

A letter has claimed that the Norwegian princess Märtha Louise was more deeply involved with a gin launched to mark her forthcoming wedding than previous stated, amid growing questions over the use of her name on the bottle.

The royal, who will marry the American businessman Durek Verrett in a four-day fjord-side wedding in Geiranger, Norway, next month, is not permitted to use her princess title in commercial contexts.
