The Princess of Wales faced a chorus of boos from anti-monarchists during her appearance at the Trooping the Colour ceremony, where she was accompanied by her children.
Princess Catherine, joined by Prince George, Princess Charlotte, and Prince Louis, remained stoic amid the jeers as they made their way through the crowds in a carriage, participating in the annual celebration.
The protest was organized by the anti-monarchy group Republic, whose members made their presence known by displaying umbrellas spelling out “Stop The Reign.”
As the royal procession moved through central London en route to Buckingham Palace, chants of “Not my King” and “Not my Queen” echoed, timed with King Charles’s official birthday celebration, despite his actual birthday being on November 14, 1948.
Despite the protests, the Princess of Wales seemed unfazed, maintaining her composure before joining the rest of the Royal Family on the Buckingham Palace balcony, where they were met with applause from the many royal supporters in attendance.
Charles’s official birthday was celebrated with a display of military pomp and pageantry on Horse Guards Parade in front of thousands of spectators.
The Prince and Princess of Wales’ youngest child Louis was spotted ducking down to look through a half-open window to catch a glimpse of Trooping the Colour, and later leaning sideways to get a better view of a celebratory fly-past.
The eight-year-old prince was watching events from the first-floor window of the Duke of Wellington’s former office with siblings Prince George, 12, and 11-year-old Princess Charlotte.
Others there included the Duchess of Edinburgh and Vice Admiral Sir Tim Laurence.

Below in the parade ground on a royal dais were the King, Queen and Kate, who wore a striking wide-brimmed blue and white Philip Treacy hat and matching Catherine Walker outfit.
The royal women paid tribute to their regiments, with Kate sporting the brooch of the Irish Guards, of which she serves as Colonel.
Camilla is Colonel of the Grenadier Guards and wore a red Fiona Clare dress based on their uniform and a black beret with white plume by Treacy, featuring her regimental cap badge.
Trooping the Colour is a historic ceremony where colours, or regimental flags, used as rallying points in battle were ‘trooped’ or paraded in front of soldiers so they would be recognised.
The ceremony evolved into a celebration of the head of state’s official birthday and this year the colour trooped was the King’s Colour of the Grenadier Guards, presented by Charles earlier this week during a Buckingham Palace ceremony.
Stands around Horse Guards Parade were filled with about 8,000 family members of the guards and officers.
Charles inspected the troops from a carriage, passing the ranks of about 1,000 guardsmen from the Grenadier, Scots, Irish and Coldstream Guards regiments and later stood to salute as the colours were marched past him.
The Duke and Duchess of Gloucester and Duke of Kent were also gathered on the Buckingham Palace balcony for the traditional fly-past of RAF aircraft.

The aerial display roared over the palace in 10 waves and featured Typhoon jets, Chinook helicopters, C-17 large military transport planes and the Red Arrows trailing their trademark red, white and blue smoke and joined by four F-35B short take-off and vertical-landing jets.
Crowds had gathered in The Mall to see the Royal Family but the area directly in front of Buckingham Palace was kept free of spectators.
The King wore his military uniform, with Queen Camilla wearing a red silk crepe Grenadier Guards uniform dress, designed by Fiona Clare, as the two travelled from Buckingham Palace to the parade grounds.
It was a family affair for the Firm as the Prince of Wales rode on horseback while wearing the Full Ceremonial Order of the Welsh Guards.Â
He was accompanied by the Duke of Edinburgh and the Princess Royal as they flashed a salute on their way to Buckingham Palace.
Highlighting the strong bond between Kate and her children, they were all dressed in complementary outfits – from George and Louis’s ties that were the exact shade of Kate’s dress to Charlotte’s printed cream dress with hints of blue.
The King was protected by the Sovereign’s Escort, made up of horseback soldiers from the Household Cavalry Mounted Regiment.Â
For the first time this year, the route was lined by armed forces members from all three branches.
As with the soldiers in the procession, all are trained and operational members of the British military.Â
The King celebrates his real birthday in November, but marks an official one with the Trooping the Colour event in June for ceremonial reasons.
