Catherine, Princess of Wales, known as Kate, will make her first public appearance since revealing her cancer diagnosis at the Trooping the Colour celebration on Saturday. She will watch the parade with her family and is expected to join other royals on the balcony. This marks a significant moment in her recovery, as it is her first public appearance since Christmas Day. Despite making good progress in her treatment, Kate expects it to continue for a few more months. King Charles III, also undergoing cancer treatment, will participate in the event from a carriage. Trooping the Colour is a grand military spectacle that has been a tradition for over 260 years, doubling as the official birthday celebration for the British sovereign. Despite challenges such as the recent horse incident, the parade is expected to proceed smoothly, with the royal family greeting well-wishers from the Buckingham Palace balcony.
