Princess Anne, the Princess Royal, has been taken to hospital after sustaining "minor injuries and concussion" at her Gloucestershire estate, Buckingham Palace has said.
GB News understands that the Princess's injuries are minor, but are consistent with those expected from an impact with a horse's head or legs.
In a statement released on Monday, Buckingham Palace said: "The Princess Royal has sustained minor injuries and concussion following an incident on the Gatcombe Park estate yesterday evening.
"Her Royal Highness remains in Southmead Hospital, Bristol, as a precautionary measure for observation and is expected to make a full and swift recovery.
"The King has been kept closely informed and joins the Royal Family in sending his fondest love and well-wishes to The Princess for a speedy recovery."
