Britain’s King Charles III Charles will take part in his annual birthday parade on horseback Saturday, the first time the monarch has ridden at the event since his mother, Queen Elizabeth II, in 1986.
The annual Trooping the Colour parade marks the British sovereign’s official birthday.
The colourful display of regimental precision and pageantry is the first of 74-year-old Charles’s reign.
Charles’s actual birthday is on November 14 but British sovereigns celebrate twice — once in private and again in public.
The June parade tradition began in 1748 under King George II, who wanted a celebration in better summer weather, as his own birthday was on October 30.
The televised event begins with a procession from Buckingham Palace to Horse Guards Parade in central London.
Some 1,400 soldiers, 400 musicians and 200 horses are taking part, led in the parade by Juno, a 10-year-old shire mare, alongside three other Drum Horses — Perseus, Atlas and Apollo.
Drum Horses are the most senior animals in the army and hold the rank of major. They are traditionally named after figures from Greek mythology.
The minutely choreographed event has its origins in the display of colours or flags of different regiments to allow their soldiers to identify them in battle.
The 1st Battalion Welsh Guards will troop, or parade, their colour up and down the ranks this year.
Highs of 25 degrees Celsius (77 degrees Fahrenheit) are forecast, but troops will likely feel hotter in their ceremonial black bearskin hats and thick red tunics.
Charles will be joined on horseback by his eldest son and heir, Prince William, his brother Edward, the Duke of Edinburgh, and sister Anne, the Princess Royal.
William inspected troops from the Household Division group of senior regiments last weekend, and the high temperatures saw several soldiers faint.
As Prince of Wales, William is honorary colonel of the Welsh Guards.
After inspecting the troops and taking a royal salute, Charles — who as head of state is commander-in-chief of the armed forces — will lead soldiers back to the palace.
He will then join other senior members of the royal family to watch a fly-past of some 70 military aircraft over the British capital, after a 41-gun salute from nearby Green Park.
