King Charles III to participate in official birthday festivities as he resumes public duties amid ongoing cancer treatment

King Charles III will join his official birthday celebrations in a little over two weeks. He is slowly getting back to his public duties while still getting treatment for cancer. Buckingham Palace confirmed this on Thursday. At the same time, there are reports that Kate, Prince William's wife, will not attend a practice for the event because she is also undergoing cancer treatment. It's not clear if the Princess of Wales will be at the main ceremony, called Trooping the Colour, on June 15. Kate hasn't shared much about her illness or treatment since she announced her cancer diagnosis on March 22. Before the Prime Minister called for a sudden election, Charles was starting to do more public duties. This unexpected event made him delay some activities that could take attention away from the election campaign. This raised questions about whether he would go to the birthday celebration. Trooping the Colour is a tradition that's been around for 460 years. During this event, soldiers in fancy uniforms walk past the king holding their special flag, called their "colour." Charles will probably go to the celebration in a carriage with Queen Camilla. He is expected to watch the ceremony sitting on a platform, not on a horse like he did last year.
