The Queen led the nation in paying its respects to fallen servicemen and women today, 100 years on from the anniversary of the start World War One.
At the Cenotaph in central London, the Queen laid a wreath following a two-minute silence in memory of Britain's killed military personnel.
Following the Queen's lead, Prince Charles, Prince William and the Duke of Edinburgh laid wreaths at the Cenotaph. David Cameron, Ed Miliband and Nick Clegg also laid wreaths, as did 46 high commissioners from Commonwealth countries.
The ceremony marked the first time an ambassador from the Republic of Ireland has participated in a wreath laying ceremony in London since 1946. The Irish ambassador to the UK, Dan Mulhall, was invited by the British government to take part in the ceremony. The government said they wanted to recognise the "immense contribution and shared sacrifice" of the Irish people who served in British forces. Around 50,000 Irish soldiers lost their lives in the First World War.
