The Princess of Wales watched the spectacle of the trooping the colour ceremony from the windows of the Major General’s office, along with her three children, Prince George, Princess Charlotte and Prince Louis, in her first public appearance since revealing her cancer diagnosis.
Catherine, who wore white with navy details, could be seen earlier smiling and talking to her children, who were dressed in navy and white, in their carriage before they arrived at Horse Guards Parade in Whitehall. The Princess of Wales, who is the regiment’s colonel, also wore an Irish guards regimental brooch. They were cheered by crowds in the Mall as they left Buckingham Palace.
King Charles and Queen Camilla were riding in a carriage in their royal procession ahead of the Princess of Wales.
The Princess of Wales was photographed prior to that arriving at Buckingham Palace by car before the parade.
Ahead of the event, Kate said in a statement: “I’m looking forward to attending the King’s birthday parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet.
“I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body and allowing myself to take this much needed time to heal.”
The Princess of Wales said she was making “good progress” but “there are good days and bad days”. “On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well.” She added that her treatment will continue “for a few more months”.
A Buckingham Palace spokesperson said: “His Majesty is delighted that the princess is able to attend tomorrow’s events and is much looking forward to all elements of the day.”
The celebration has been held on the sovereign’s birthday for more than 260 years. At the event, Number 9 Company, Irish guards, a regiment Kate represents as colonel, will be trooping the king’s colour.
In a letter read to the regiment last week, the Princess of Wales, who is undergoing chemotherapy, wrote to the Irish guards to apologise for being unable to take the salute and wished them luck. Lt Gen Sir James Bucknall will take the salute on her behalf.
The king, who is also undergoing treatment for cancer, will not ride on horseback during the ceremony, but will instead review the parade from an Ascot landau carriage. He attended his first trooping at the age of three, riding in a carriage with his grandmother, Queen Elizabeth the Queen Mother.
More than 1,250 soldiers and hundreds of Guardsmen assembled on the parade ground to be inspected by the King from his carriage with Queen Camilla, who is colonel of the Grenadier Guards, and accompanied by the mounted royal colonels.
The stands overlooking the parade ground were filled with about 8,000 family members and partners of the guardsmen and officers on parade.
