King Charles has used his annual TV message to give personal thanks to the medical staff who have cared for him this year.

King Charles III used his annual Christmas message Wednesday to hail the selflessness of those who have cared for him and the Princess of Wales this year, after both were diagnosed with cancer. The 76-year-old monarch said he and his family are “continually” impressed by those who dedicate their lives to helping others.

As Charles put it, “I am deeply grateful, too, to all those who have offered us their own kind words of sympathy and encouragement.”
