The soldier who tragically died after a display at the Royal Windsor Horse Show has been named. Ciara Sullivan was a member of the King's Troop.

Royal Horse Artillery’s Sullivan suffered serious injuries after a fall during a display at the Royal Windsor Horse Show. The King, who was at the event, was “greatly shocked” and “saddened” to have learned of the death, a Buckingham Palace spokesperson has said, adding that Charles will be in touch with her family to share his condolences.

A Buckingham Palace spokesperson said: “While His Majesty and other Members of The Royal Family were present at the arena at the time the incident took place, they were not made aware of the severity of the situation until later.

“The King was greatly shocked and saddened to have learned subsequently of the Troop member’s death, and will be in touch with the family to share his personal condolences. The thoughts and most heartfelt sympathies of the whole Royal Family are with the victim’s loved ones and military colleagues at this time of grief.”

Despite being given immediate medical treatment, the soldier sustained serious injuries and sadly died at the scene, Thames Valley Police said on Saturday. The Buckingham Palace spokesperson said that His Majesty will be in touch with the family of the victim to share his condolences.

Police added it is treating the death as unexplained but non-suspicious.

Ciara Sullivan's father Pat shared a photo of her daughter on social media alongside a message, which read: "The honour. The service. They will never be forgotten."

A friend, Eleanor Lucas Bell, also paid tributes and spoke of Sullivan's "incredible talent, horsemanship and dedication".

She wrote on Facebook: "Today our sport lost one of its very best. The soldier who tragically lost her life at Royal Windsor Horse Show was someone known to us personally. She had ridden my boys, and I saw first hand the incredible talent, horsemanship and dedication she possessed.

The Royal Windsor Horse Show was first staged in 1943 to help raise funds for the World War 2 effort. The inaugural show was attended by members of the Royal Family, including King George VI, Queen Elizabeth (the Queen Mother) and the two young princesses, Elizabeth and Margaret.
