• Remembrance Sunday in the UK commemorates those who have died in world wars and other conflicts.
• Following tradition, the royal family gathered at the Cenotaph to mark the solemn event.

On Sunday, senior members of the royal family – including Princess Anne, Prince Edward, Prince William, and King Charles – took part in the annual Remembrance Sunday ceremony at the Cenotaph in London, UK.
