Princess Caroline of Monaco is to follow in the footsteps of Audrey Hepburn and Angelina Jolie by becoming a United Nations Goodwill Ambassador.
The Monegasque royal was chosen for the role in recognition of her "personal commitment to the protection of children and the family", said UNESCO Director General Koichiro Matsuura.
The 46-year-old princess will be formally appointed in a ceremony in Paris next Tuesday. It is expected that she will concentrate her efforts on a UNESCO project to promote vocational training for women and girls in sub-Saharan Africa and Asia.
As head of the Princess Grace Foundation, Caroline has been actively campaigning for children's rights for over 20 years. The foundation was first set up by Caroline's mother in 1964 to help disadvantaged people who fall outside the remit of other social organisations.
Since Caroline took over in 1983, it has given special attention to the plight of young people around the world.
