King Charles and Duchess of Edinburgh were at the Royal Windsor Horse Show when a soldier  died after falling from his horse.

According to The Sun, the member of the King’s Troop, Royal Horse Artillery, suffered serious injuries when he  fell yesterday evening as he exited the arena in Windsor, Berkshire.

The outlet reported that although King Charles was present on the occasion, it's not clear whether he witnessed the incident. 

A 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.”

Thames Valley Police said, "We are appealing for information following an unexplained but non-suspicious death yesterday. Anyone with information or material relating to this death should get in touch."

The Royal Windsor Horse Show is continuing as planned, without The King’s Troop, Royal Horse Artillery display, The Sun reported.
