King Charles and Queen Camilla led the royal family’s public tribute on what would have been Queen Elizabeth II’s 100th birthday, with engagements in London that blended remembrance, design and family unity. The day centered on plans for a national memorial, the opening of a new garden in Regent’s Park, and a Buckingham Palace reception attended by senior royals. Prince William and Catherine, Princess of Wales, joined the occasion, while Princess Anne carried out a separate engagement tied to the late monarch’s legacy of service and duty.
