Queen Elizabeth 11 was among the dignitaries
taking part in commemorations across the United Kingdom to honor the war dead, officials said.
The Queen led Remembrance Sunday service at the Cenotaph in London, where party leaders and thousands of current and former military personnel joined her, the BBC reported.
Prince William earlier attended a service of remembrance in Afghanistan, and the British Legion said it sold a record 46 million poppies this year.
This year's observation held added significance after a year of heavy British military losses in Afghanistan, the report said.
Additionally, this year is the 90th anniversary of both the Cenotaph and the Tomb of the Unknown Warrior, who is buried in Westminster Abbey.
Veterans attending the ceremonies included Ronald Meade, 89, of the Burma Star Association.
He said he was chosen to carry a wreath during observations "because our numbers are dwindling . but as long as I've got my health, I'll keep
coming."
After two minutes of silence, the queen laid a wreath at the Cenotaph; she was followed by other members of the Royal Family, Prime Minister David
Cameron, Liberal Democrat leader Nick Clegg, and opposition leader Ed Miliband.
