The Duchess of Rothesay will present an honorary degree to her sister-in-law, the Princess Royal, next month.
Camilla is the chancellor of Aberdeen University, and will bestow the honour on Princess Anne at a special event at the institution on January 14.
It recognises her charity work over the last 50 years – which spans across more than 300 organisations in the UK and overseas.
The Princess Royal is patron of Save the Children, a charity she served as president for 46 years, visiting projects in China, Cambodia, Botswana, Madagascar and the Philippines.
Professor Janet Darbyshire will also receive an honorary degree at the ceremony in recognition of her work in clinical sciences over 40 years.
Previously director of the Medical Research Council Clinical Trials Unit, Prof Darbyshire’s study of diseases such as HIV and tuberculosis has led to improvements in prevention and treatment across the world.
A special Principal’s Award for Outstanding Service to the Community will also be presented to the Denis Law Legacy Trust – which provides free outreach projects to children and young people through its Streetsport project.
Aberdeen-born former Manchester United and Scotland footballer Mr Law will be among trust representatives in attendance.
Mr Law became the only Scottish player to win the prestigious FIFA Ballon d’Or European Footballer of the Year in 1964.
The work of his eponymous legacy trust has made major strides in reducing instances of youth crime and antisocial behaviour, promoting health and well-being and encouraging inclusivity through sport, physical activity and creative endeavour.
Professor George Boyne, principal and vice-chancellor at the university, said: “The University of Aberdeen’s foundational purpose dedicates this institution to acting ‘in the service of others’.
“Honorary degrees and special awards are our way of acknowledging people who have made exceptional contributions to the service of others, and I am delighted we are recognising the Princess Royal, Professor Janet Darbyshire and the Denis Law Legacy Trust in this way.”
