FILE - Britain's Queen Elizabeth and Prince Charles arrive for the State Opening of Parliament at the Houses of Parliament in London, Thursday Dec. 19, 2019. After spending much of his adult life in the shadow of Queen Elizabeth II, Prince Charles has taken on a greater public role in recent years, increasingly standing in for his mother in her twilight years. In May, he presided over the state opening of Parliament, the most public symbol of the monarch’s role as head of state. (Toby Melville, Pool via AP, File)
