All she was concerned about today was the applause of her people as she and her husband were driven through the streets of the Tongan capital, Nuku’alofa, in an open-topped car.

The government and royal officials have long been against marriage between cousins – as well as between royals and commoners - but Prince Tupouto’a has told his advisers that love comes before protocol.
