This film offers a glimpse into the world of official suppliers to the royal family.
From cheese to chocolate and books to bespoke suits, with stores being members of an exclusive group who have the right to display a royal coat of arms.
It may not surprise you to learn that among the hundreds of companies that the royal family patronise are eight champagne houses.
But also on the list of royal warrants, there’s a scaffolding company, a sacks supplier, a broomstick maker and Weetabix (so now we know what the Queen has for breakfast).
With the exception of new technology firms, they’re all well-established companies, many dating back to the 1800s and even the 1700s.
