Kate Middleton plans next public appearance after Trooping the Colour Kate, the Princess of Wales, is set to make another major appearance after stunning the onlookers…

London, United Kingdom –

London put on a display of birthday pageantry Saturday for King Charles III, a military parade that marked the Princess of Wales ‘ first public appearance since her cancer diagnosis early this year.

The annual event was also a show of stability by the monarchy after months in which both the king and Kate, wife of heir to the throne Prince William, have been sidelined by cancer treatment.

In a symbolic display of unity, Charles, Queen Camilla, William, Kate and their children were joined by other members of the royal family on a Buckingham Palace balcony at the end of the King’s Birthday Parade. The family waved to the gathered crowd as they watched a flyby of military aircraft to cap ceremonies marking the monarch’s official birthday.

It was the first time Kate has appeared in public since December. She disclosed in March that she was undergoing chemotherapy for an unspecified form of cancer.

“I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days,” Kate said in a statement released Friday, adding that she faces “a few more months” of treatment.
