Queen Camilla, 77, has stepped back from royal duties this week due to a chest infection. Buckingham Palace announced her need for rest per doctors' advice. She aims to recover in time for weekend Remembrance events, including the Field of Remembrance and a reception for Olympic athletes. The Duchess of Gloucester will cover her duties. The announcement coincides with ongoing health concerns for King Charles, who is undergoing treatment for cancer, and echoes earlier health issues faced by Princess Kate, adding to the royal family's current health challenges.
