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, 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.
