King Charles made a public appearance for the first time since it was revealed he was suffering from cancer. Prince Harry flew into London to see him as Buckingham Palace announced that Charles, 75, would postpone public engagements to undergo treatment. Harry, who has been estranged from his father and the rest of the royal family, arrived in Britain to visit his father as messages of support for the king poured in from world leaders. Charles smiled and waved as he was driven from his Clarence House home in central London to Buckingham Palace. Although there are no plans for Harry to see his elder brother, Prince William, while in Britain, William is expected to fulfill some of the monarch’s duties while Charles begins treatment. While the palace did not give further details about the cancer, it was announced that it was not prostate cancer and was caught early. Charles plans to continue with much of his private work as monarch, but the diagnosis has drawn attention to Britain’s rising cancer waiting times in the state-run National Health Service. The surprise diagnosis comes as Kate, the Princess of Wales, recuperates at home after spending two weeks in the hospital for non-cancerous abdominal surgery. The absence of senior figures will put pressure on working royals to perform extra engagements. Despite the upheavals surrounding the royal family, the nation wishes King Charles a speedy recovery.
