Queen Camilla was absent from multiple royal family events amid her recovery from a chest infection .

LONDON — King Charles III led the nation Sunday in a two-minute silence in remembrance of fallen service personnel in central London as the Princess of Wales looked on, a further sign the royal family is slowly returning to normal at the end of a year in which two of the most popular royals were sidelined by cancer.

Kate Middleton made a rare appearance today amid her cancer recovery, joining the royal family for the National Service of Remembrance—the formal observance of Remembrance Sunday at the Cenotaph, a war memorial in London.

Kate, 42, appeared on one of the three balconies next to Sophie, the Duchess of Edinburgh, at the ceremony. She watched as her husband Prince William, 42, and father-in-law King Charles III, 75, laid wreaths as a tribute to armed forces members who have died in duty.

An emotional Princess of Wales completed a milestone in her return to royal duties on Sunday, as she joined other members of the royal family at the Cenotaph. The appearance marks the first time Kate has carried out commitments on two consecutive days since she was diagnosed with cancer at the beginning of the year.

King Charles III led Remembrance Day commemorations in London on Sunday as the United Kingdom remembered British and Commonwealth servicemen and women who have lost their lives to conflict.
