The Queen’s daughter, the Princess Royal, observed a 41-gun-salute in Hyde Park on Monday afternoon to mark the occasion of her mother’s 93rd birthday.
Princess Anne greeted the King’s Troop Royal Artillery soldiers in the park as they prepared to fire the canons to celebrate the occasion.
The 68-year-old royal arrived in Hyde Park by a horse-drawn carriage wearing a tartan coat and feathered hat.
The Honourable Artillery Company also performed a further 62-gun salute at the Tower of London.
Gun Salutes never take place on a Sunday. As such, the mark of respect had been postponed by a day.
Taking to Twitter, the Tower of London staff explained why a 62-round gun salute was fired this afternoon.
Twenty-one rounds are fired for a royal anniversary, an extra 20 as the Tower is a royal palace and fortress, and a further 21 rounds for the City of London.
