People laid wreaths at memorials across the country and held a two-minute silence to remember the UK's veterans of armed conflict.
British armed forces personnel and politicians gathered for an annual service at the Cenotaph memorial at Whitehall, central London, with crowds of ordinary people wearing poppies also in attendance.
Prince Charles laid a wreath at the cenotaph on behalf of his mother, the Queen. The head of state and other members of the Royal Family looked on from the balcony of the Foreign and Commonwealth Office building.
Moved to tears listening to war stories on BBC1.

The service began when Big Ben chimed at 11am. Gun salutes from First-World War-era artillery marked the beginning and end of a two minutes' silence. Buglers of the Royal Marines played the Last Post, a traditional call of the British Armed Forces which is played during memorial services.
