The reigning monarch admitted he has found himself welling up at the kindness he has received from the public since officially revealing his health news. King Charles, 75, met with British Prime Minister, Rishi Sunak on Wednesday afternoon at Buckingham Palace. After the PM said it was "wonderful" to see King Charles looking so well, the monarch told him any appearance of wellness was just an illusion. "It's all done with mirrors," Charles quipped. The PM went on to offer his support, saying, "Well, we're all behind you. The country's behind you." And King Charles was candid about his feelings.
