Just as they have since 1919, Commonwealth nations observed two minutes of silence at the 11th hour of the 11th day of the 11th month.
The Queen was the first to lay a wreath at the Cenotaph, followed by Prince Philip and Prince William (right), then other senior members of the Royal Family, politicians and high commissioners from other countries.
From a balcony, the service was watched by Catherine, Duchess of Cambridge; Sophie, Countess of Wessex, and Princess Anne's husband, Sir Timothy Lawrence.
Missing was Prince Harry, who is on a four-month tour with British troops in Afghanistan, and Prince Charles, who attended ceremonies in New Zealand, where he and Camilla are on a two-week royal tour.
About 10,000 veterans marched past the Cenotaph in the ceremony that was first since the last surviving veteran of the First World War, Florence Green of Britain, died in February at age 110. Canada's last First World War veteran, John Babcock, died in 2010.Prince Charles meets veterans as New Zealand Prime MinisterJohn Key looks on after an Armistice Day Commemoration at the Auckland War Memorial.
