Queen's granddaughter breaks arm
Lady Louise Windsor, one of the Queen's granddaughters, has broken her left arm after falling off her pony while riding, Buckingham Palace said.
The royal, aged eight, has been treated at an undisclosed hospital and is now resting at her parents' home following the accident.
It is thought the incident happened in the grounds of Windsor Castle, but the Queen - who is staying at the royal residence - was not with her granddaughter when she fell.
A Buckingham Palace spokeswoman said: "Lady Louise broke her left arm after falling from her pony while riding at Windsor this morning.
"She has been treated by doctors and is now resting at home.
"The Countess of Wessex was supposed to go to Manchester today with the Earl, but understandably stayed with her daughter."
The young royal was wearing a hard hat when the accident happened and would have been under the supervision of an adult.
Edward and Sophie live at Bagshot Park, a large country estate near the Queen's Berkshire home of Windsor Castle, with their daughter and four-year-old son Viscount Severn.
Lady Louise was last seen in public at the traditional Easter service at St George's Chapel, Windsor Castle, on Sunday with the Queen and other senior royals.
