As we all know, Yorkshire has some of the best producers of food, drinks and clothes in the country - but it's always nice to get a Royal seal of approval.
And that takes the form of the Royal Warrant. To be issued a Royal Warrant allows the company to display the royal arms on their products.
The Queen decides who is able to grant a Royal Warrant to businesses, and these are known as Grantors. The current Grantors are The Queen herself, and William, the Prince of Wales. Previous Grantors have included The Queen Mother and The Duke of Edinburgh.
Here are the Yorkshire businesses which hold a Royal Warrant.
