The King and Queen were in good spirits as they were joined by jockey Frankie Dettori in the royal procession on the final day of Royal Ascot.

Racegoers cheered as Charles and Camilla led the traditional carriage procession in the parade ring on Saturday, with Mr Dettori in the rear carriage with his wife Catherine, and trainer Jamie Snowden and his wife Lucy.

The popular jockey, who is due to retire this year, had a number of rides this week on horses owned by the King and Queen and failed to win, but took the big prize with 15-2 shot Courage Mon Ami in his ninth Gold Cup on Friday.

Lord and Lady Frederick Windsor joined the procession in the second carriage at the Berkshire meet, with Lady Frederick and Camilla spotted chatting warmly to each other.

Camilla wore a long-sleeved cream dress and wide brimmed hat, while Charles looked smart in a morning suit and top hat.

When the King and Queen and their guests stepped down from the carriages in the parade ring, they mingled with trainers and jockeys ahead of the first race.

The Earl and Countess of Caledon joined Charles and Camilla in the first carriage.

Lady Gabriella Kingston, the daughter of Prince and Princess Michael of Kent, travelled with her husband Thomas Kingston in the third carriage.

They were accompanied by Andrew Balding, the trainer of Charles’s horse King’s Lynn, which will compete on Saturday for the Wokingham Stakes, and his wife, Annalisa.

A short film in remembrance of the late Queen Elizabeth II at Ascot played before the procession began.
