The King has told of his "shock and sadness" after a soldier died following a fall from a horse at the Royal Windsor Show.
Thames Valley Police said they had found "no suspicious circumstances" in the death of the soldier from the King's Troop, Royal Horse Artillery on Friday evening.
The soldier was given treatment for "serious injuries" after falling from the horse as it left the arena, but died at the scene. The soldier's next of kin have been informed.
A Buckingham Palace spokesperson said the King was "greatly shocked and saddened" to have learned of the death, adding that Charles "will be in touch with the family to share his personal condolences".
The King attended the horse show on Saturday, a day after the tragic incident.
An Army spokesperson said: "It is with deep regret that we announce a member of the King's Troop Royal Horse Artillery died on Friday 15 May, following a tragic incident at the Royal Windsor Horse Show.
"The family has been notified, and our thoughts are with them at this sad and difficult time."
