Millions of people across Britain will remember those who have died in war as a two minute silence is held on Friday to mark Armistice Day.
The silence, at the 11th hour of the 11th day of the 11th month, represents the moment when all guns stopped at the end of World War I.
The public will fall silent as Big Ben chimes at 1100 GMT.
Britain's oldest veteran, 109-year-old Henry Allingham, will lay a wreath at a British memorial in France.
It is the first permanent memorial to British air personnel who served on the Western Front.
Mr Allingham, who is the last survivor of the Battle of Jutland and the last surviving founder member of the Royal Air Force, will be joined by Air Vice Marshal Peter Dye, the RAF's deputy commander-in-chief, and 12 aircraft engineer trainees from RAF Cosford, near Wolverhampton.
Wreaths will also be laid at the Memorial Gates on Constitution Hill in London to mark the 60 year anniversary of the end of the World War II, as well as Armistice Day.
'Rare moment'
Metropolitan Police Commissioner Sir Ian Blair; Field Marshal Sir John Chapple, who will lay a wreath on behalf of Prince Charles and the Gurkhas, and Minister of Armed Forces Adam Ingram are due to attend.
The London Eye will be illuminated in red to mark the day. It will stop moving as those inside - schoolchildren accompanied by World War II veteran Len Jeans - pay their respects.YThe two minute silence is the single biggest annual demonstration of public support for any cause in the country

Lloyds of London will ring the Lutine Bell to mark the start and finish of the two minute silence.
Following that, the Last Post will be played and Lord Peter Levene, chairman of Lloyds, and a representative from the Royal British Legion will lay two wreaths in the famous Underwriting Room.
A ceremony will also be held to honour the five million people from India, Pakistan, Sri Lanka, Bangladesh, Nepal, Africa and the Caribbean who fought in both world wars.
Stuart Gendall, from the Royal British Legion, said: "The two minute silence is the single biggest annual demonstration of public support for any cause in the country.
"This small yet significant individual and collective act is a rare moment when the nation can stand together and reflect upon the price of freedom."
