The Queen is to lead the nation in commemorating the sacrifices made by Britain's Armed Forces at the Remembrance Sunday ceremony.
The monarch will be joined by other members of the Royal Family, Prime Minister David Cameron and opposition party leaders at the wreath-laying event at the Cenotaph in Whitehall.
After the two-minute silence, the Queen will lay the first floral tribute followed by the Duke of Edinburgh, the Prince of Wales, Prince William, the Duke of York, the Earl of Wessex, the Princess Royal and the Duke of Kent.
Next to pay their respects will be Mr Cameron, Liberal Democrat leader Nick Clegg, Labour chief Ed Miliband, leaders of other parties, commissioners from Commonwealth countries and defence chiefs.
Thousands of ex-servicemen and women and civilians are expected to take part in a march past the Cenotaph.
It comes after the annual Festival of Remembrance on Saturday night where the Queen, senior members of the Royal Family and the Prime Minister joined an audience of veterans and their families to honour Britain's war dead at the Royal Albert Hall.
The evening was hosted by the Royal British Legion and was both a moving tribute to the fallen and a celebration of their memory through music and song.
A highlight of the festival was the Book of Remembrance being carried into the hall by Royal Marine Lance Corporal Ram Patten, accompanied by the "March For Honour" teams who have been trying to raise £1 million for the Legion.
The serving and ex-servicemen have been marching across the UK since November 4 in four groups - walking a mile for every British military life lost on operations in Iraq and Afghanistan since 2001.
The Festival of Remembrance, held annually since 1927, culminated in the traditional release of thousands of scarlet poppy petals from the roof of the Albert Hall to represent all those who have died in combat.
