The Trooping the Color ceremony is in full swing at Horseguards Parade, with King Charles, Queen Camilla, royals and the Prime Minister among the spectators.
King Charles appeared in high spirits as instructed by the royal family before taking to the balcony of Buckingham Palace for a Red Arrows flyover.
The British monarch was greeted with a salute as he inspected soldiers and military personnel at the annual event marking the sovereign’s official birthday.
The bands were in full display, carefully maintaining formation while simultaneously playing their drums and trumpets during a slow march that took place across the square.
The king wore the uniform of the Grenadier Guard, the regiment paraded in colors; Queen Camilla dazzled in a red silk crepe dress.
The royal family shared the first look of the King and Queen as they inspected the Parade.
Large crowds have gathered to try to catch a glimpse of the Royal Family, with many raising their phones and waving at the procession.
The Princess of Wales was also seen greeting royal watchers alongside her three children in an open carriage along The Mall.
Catherine stunned in a pale blue jacket designed by Catherine Walker with a Philip Treacy hat and an Irish Guards brooch.
Meanwhile, Prince William rode a horse alongside his uncle and aunt, Prince Edward and Princess Anne.
