At 75, the Princess Royal serves as a Counsellor of State and remains a close ally to her brother, the King. Charles, now 77, acceded to the throne after his mother’s death in 2022 and was crowned the following May in a ceremony that blended modern touches with long-standing tradition.
The anniversary follows a busy period for the monarch: a state visit to the U.S. in April 2026 that included a White House welcome and a Congressional address, and public updates about his health after a February 2024 announcement of cancer treatment. Princess Kate later disclosed her own diagnosis and has since reported being in remission. The heir remains Prince William, followed by Prince George.
