Queen Camilla has pulled out of public engagements on doctors’ orders, having become “unwell with a chest infection,” Buckingham Palace announced. The 77-year-old has had to cancel a high-profile remembrance event on Thursday, but hopes to be well enough to attend Britain’s main Remembrance Sunday service at the Cenotaph in London this weekend. The queen’s illness comes after a turbulent year in which both King Charles III and Princess Kate were diagnosed with cancer.
