A member of the Royal Family can become a representative or supporter of an organisation as a patron, working to publicise and recognise the group’s work.
Family members have become linked to thousands of groups, with additional requests from organisations pouring in to Buckingham Palace every year.
While some organisations, like The National Portrait Gallery and Arthritis Research UK, are well-known, others like the Anglo-Finnish Society and Beanstalk, are less so.
Most Royal Family members have limited the number of organisations that they support.
Many were inherited from previous Monarchs.
