King Charles III spoke about the “uncertainties and anxieties of illness” as he delivered his annual holiday message from a former hospital chapel, a poignant location given the king’s ongoing cancer treatment.

King Charles III was diagnosed with cancer this year after treating an enlarged prostate. His daughter-in-law, Kate Middleton, completed chemotherapy in September.

King Charles III is expected to use his annual Christmas message to highlight health workers, at the end of a year in which both he and the Princess of Wales were diagnosed with cancer.
