Prince Harry and Meghan are said to be planning to relocate from the U.S. later this month to a private residence outside London.
The king's cancer diagnosis was announced publicly in February 2024.
Buckingham Palace also released a new photograph of the King in honor of his big day.
All eyes were on Princess Kate Saturday as she made her first public appearance since her cancer diagnosis early this year.
A recently unveiled portrait of King Charles was vandalized in a London museum on Tuesday by an activist animal rights group, the group said.
The King's audio message were his first public comments since Catherine revealed she was undergoing chemotherapy. The princess' announcement put an end to months of speculation over her health.
