The Queen and her family stepped out for one of the finest events in the British royal calendar on Tuesday – Royal Ascot. Her Majesty was in high spirits as she attended the opening day of the races, wearing a vibrant, hard-to-miss outfit. She was joined by various members of her family and led the royal procession around the racecourse, riding in the same carriage as the king and queen of the Netherlands and the Duke of York.
The Duke and Duchess of Cambridge, who was on maternity leave during last year's Ascot, supported the Queen, as did the Prince of Wales and the Duchess of Cornwall. The Earl and Countess of Wessex also stepped out at Ascot, as did Princesses Beatrice and Eugenie.
Ascot is loved by fans just as much for the exciting horse races as the style stakes, and this year the royal family did not disappoint. See the best photos below…
Some 300,000 racegoers are expected to descend on the Berkshire racing meet over the next five days. Writing in the opening day's official race programme, the Queen said: "Racing began at Ascot over 300 years ago and while much has changed, the horses remain the stars, thrilling us with their beauty, brilliance and courage. The quality and depth of competition at the royal meeting has also continued to prosper, with eight group one races taking place this week.
"The best horses and jockeys from across the globe are increasingly drawn to Royal Ascot, and it is truly exciting to welcome competitors from overseas, as strong international competition adds further interest and fascination."
