THIMPHU - Britain's Duke and Duchess of Cambridge arrived on Thursday in the tiny Himalayan kingdom of Bhutan, where they will meet its glamorous young royal couple for the first time.

Prince William and wife Kate touched down at Bhutan's only international airport, nestled deep in a river valley, to be welcomed by members of the royal family and receive flowers from a boy and girl wearing traditional dress.

Bhutan's fifth king, Jigme Khesar Namgyel Wangchuck, and Queen Jetsun Pema will meet the British royals in a private audience and later host them to dinner, besides treating them to a display of archery, the national sport.
