The Duchess of Cambridge will train for a fixed wing licence in Anglesey, where her husband William is an RAF helicopter pilot.
Both he and his brother are qualified instructors but Harry offered to take the future Queen up because of William’s hectic schedule.
“Wills’ diary is manic and to be honest, would any wife want to be taught by their husband?” the Sun quoted a Royal source as saying.
“Harry immediately offered and the Duchess is thrilled,” the source added.
