King Charles III presides over the annual commemoration in Britain for the first time as a monarch.
The King attends the service with Camilla, the Queen Consort and other members of the Royal Family at The Cenotaph in central London.
The King laid a new wreath at the Cenotaph, the design of which is a tribute to the wreaths of his grandfathers, King George VI and Queen Elizabeth II.
The wreath’s poppies are mounted on black leaves, as is tradition, and his banner bears the king’s racing colors of scarlet, purple and gold.
Camilla watched the moment from the balcony of the Foreign, Commonwealth and Development Office. For the first time, a wreath was laid on her behalf.
The wreaths of the king and queen consort were accompanied by handwritten cards with the new ciphers.
A nationwide two-minute silence was observed at 11 a.m. local time (6 a.m. ET), marked by the toll of Big Ben — which has now officially opened after a five-year restoration project.
Other royals attending the service include William and Kate, the Prince and Princess of Wales, Edward and Sophie, the Earl and Countess of Wessex and Princess Anne.
Sunday’s event also featured a parade of around 10,000 veterans from the Royal British Legion, including veterans from the Second World War and those who have served in conflict since.
The annual service is held on the Sunday following November 11 – the day the First World War ended in 1918.
The event commemorates all those who have fallen in conflict.
On Saturday night, members of the royal family, including Charles, Camilla, William and Kate, attended the Royal British Legion’s annual memorial service at the Royal Albert Hall. A video tribute was paid to Queen Elizabeth as part of the event, which also marked the 40th anniversary of the Falklands War.
Charles, 73, became Britain’s king after his mother’s death in September. His coronation has been scheduled for next May to allow time to mourn Elizabeth’s death and to plan the ceremony.
