Remembrance Sunday events will be held across the country today in tribute to members of Britain and the Commonwealth's Armed Forces who have died during conflicts.
The Queen will attend a service at the Cenotaph in Whitehall, where she will lay a wreath in memory of those who have made the ultimate sacrifice.
She will be joined by a host of senior royals, Prime Minister David Cameron and leaders of opposition parties for the service, a focal point of the nation's Remembrance Sunday ceremonies.
The first stroke of Big Ben at 11am and the firing of a gun from Horse Guards Parade by The King's Troop Royal Horse Artillery will mark the start of two minutes' silence, which will be followed by The Last Post, sounded by the Buglers of the Royal Marines.
The Queen will then lay the first wreath, followed by the Duke of Edinburgh, the Duke of Cambridge, the Duke of York, the Earl of Wessex, the Princess Royal, Prince Michael of Kent and Field Marshal Lord Guthrie of Craigiebank.
The Prince of Wales and Duchess of Cornwall are unable to attend as they are in New Zealand on a Jubilee tour.
