The tradition of ceremonies at the Cenotaph began in 1920, as Nick Higham reports
More than 10,000 military veterans and civilians will march past the Cenotaph later to mark Remembrance Sunday.
For the first time, their number will include representatives of a World War Two unit known as "Churchill's Secret Army".
The Queen will lead the nation's commemorations from Whitehall.
A two-minute silence will be observed by military veterans and senior officers, political and religious leaders and Commonwealth dignitaries.
