Queen Camilla has awarded royal warrants to a number of members of her fashion and beauty team

In addition, she has granted a royal warrant - which is given as a mark of recognition to people or companies who have regularly supplied goods or services to the royal household and allows them to advertise their links to the crown - to milliner Philip Treacy, dressmakers Anna Valentine and Fiona Clare, and couturier Roy Allen.

The queen also granted a warrant to Benson and Babb veterinary practice, which previously held a warrant from her husband when he was still Prince of Wales.

Deborah admitted the warrant is an "incredible" accolade, which will particularly help with foreign experts.

She explained how the queen - who first contacted her shortly after her marriage to King Charles in 2005 - was the first person to try her coveted bee venom mask.

She told the Daily Telegraph newspaper: "The queen was the first to try it when I made it.

"I handmake the products and do her treatments as well. Her new favourite is collagen drops - which you drink - and she is still using the bee venom."

And Anna, who designed the queen's wedding dress, said she was "honoured" to have been granted a royal warrant.

She said: "It is a wonderful recognition for the team of 16 highly skilled artisans employed at the Anna Valentine atelier in Marylebone, and a testament to Her Majesty's loyalty, which is greatly appreciated."

Charles and Camilla granted royal warrants to almost 400 companies from a diverse range of industries, with the king's list including 386 companies which previously held a warrant to his late mother Queen Elizabeth.

Royal warrants are granted for up to five years at a time.
