Princess Anne, sister of King Charles, suffers concussion, palace says

Princess Anne has suffered minor injuries and a concussion following an incident at her country home, Buckingham Palace announced Monday.

Anne, who is the 73-year-old sister of King Charles III, was hospitalized but is expected to make a full recovery. The incident at the Gatcombe Park estate happened on Sunday evening.

"Her Royal Highness remains in Southmead Hospital, Bristol, as a precautionary measure for observation," Buckingham Palace said in a statement, adding that "The King has been kept closely informed and joins the whole royal family in sending his fondest love and well-wishes to The Princess for a speedy recovery." 

The princess was walking within the protected perimeter of the estate when the incident occurred, Britain's Press Association said. Her medical team added that her head injuries were consistent with a potential impact from a horse’s head or legs, according to The Associated Press.
