Britain's Prince Charles has praised Duchess Catherine for her Scouting activism.
The heir to the throne is proud of his daughter-in-law's work as a volunteer leader in the Scout Association, a role she adopted in January 2012.
Writing in the Mail on Sunday newspaper, Charles said: "I need hardly say that I am particularly delighted that my daughter-in-law has helped to swell the ranks of much-needed Scout volunteers, since enrolling many more adults as leaders is the greatest need for so many of our youth organisations."
Catherine joined her local Brownies group in Bradfield Southend, Berkshire, when she was eight years old, so the Scouting and Guiding movement and its aim to support young people in their physical, mental and spiritual development has long been close to her heart.
The Duchess of Cambridge's involvement has led to over 2,800 people to volunteer their services to help the movement, which was set up in 1907 by Lord Baden-Powell and focuses on practical outdoor activities.
In March, the 31-year-old royal - who gave birth to her first child, Prince George, in July - met a troop in the Lake District to partake in a day of outdoor adventures.
She also attended in a ceremony honouring the Scouts at Windsor Castle, where Chief Scout and TV personality Bear Grylls branded her an "incredible role model".
