Charles offered his “heartfelt thanks” to medical staff who offered “strength, care and comfort” during cancer treatment

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.

The British monarch recorded his annual holiday address from the chapel of a former hospital, rather than from a palace.
