Prince Harry and Prince William "pleaded" with their father, King Charles, not to marry the future Queen Camilla, the Duke of Sussex wrote in his memoir, 'Spare.'

It was the first meeting between King Charles, the head of the Church of England, and the pope since the monarch ascended to the throne in 2022.

King Charles III and Queen Camilla will celebrate their 20th wedding anniversary in Rome on Wednesday. The king began a four-day state visit to Italy on Monday, where he will address parliament and tour the Colosseum. However, an audience with Pope Francis was called off due to the pontiff's ill health.
