King Charles III has made his most significant outing since his cancer diagnosis last month, attending the traditional Easter Mattins church service in Windsor on Sunday. Charles, 75, appeared to be in good spirits as he arrived by car to St. George’s Chapel, a 14th-century building on the grounds of Windsor Castle, around an hour’s drive from London. He was accompanied by his wife, Queen Camilla, for the event – a staple in the royal calendar. https://cnn.it/3TGoKOx
