Kate Middleton, Colonel of the Irish Guards, has written a heartfelt letter apologizing for her absence at a major Trooping The Color rehearsal. This comes after the Duchess revealed her battle with cancer in March, leading to her withdrawal from public appearances. Despite expressing her pride and admiration for the Regiment, Middleton regrets missing out on the Colonel's review and Trooping of the Color event in June. Lieutenant General James Bucknall will step in for her, with uncertainty surrounding her attendance at the parade. While unsure of her future public appearances, the Irish Guards were deeply moved by Middleton's message, wishing her a speedy recovery and eagerly awaiting her return. The princess's absence highlights her dedication to her role as Colonel and her desire to continue representing the Irish Guards with honor and pride.
