Upon the death of Queen Elizabeth on Sept. 8, Charles immediately acceded to the throne and named his eldest son the Prince of Wales, the traditional title for the heir, the following day. And although the two don't have a traditional father-and-son relationship, they are now closer than ever before. "Talking about the future of the country and their future roles has strengthened their bond," a source who knows both Charles, 73, and William, 40, tells PEOPLE in this week's cover story. In addition to coming together over the deaths of Prince Philip, Charles' father who died in April 2021, and Queen Elizabeth, Prince Harry and Meghan Markle's decision to move to California after stepping back as senior members of the royal family in 2020 has "brought [William and Charles] closer," says the source.
