The Duchess of Cambridge is to become a volunteer helper with the Scouts as part of a new package of five royal patronages.
Kate will wear the Scout Association's distinctive blue shirt, scarf and woggle as she lends a hand at meetings close to the rented farmhouse she shares with Prince William on Anglesey.
She will also be required to take the Scout Promise - vowing to "do my best to do my duty to God and to the Queen, to help other people and to keep the Scout Law."
Founded by Robert Baden-Powell in 1907 to help young people with their "physical, mental and spiritual development," the Scouting movement requires members to be loyal, friendly, courageous and considerate - as well as keeping to the famous motto "Be Prepared."
Kate, whose 30th birthday is on Monday, does have some experience because, at the age of eight, she enrolled as a Brownie with the 1st St Andrew's pack in Pangbourne, Berkshire.
