Members of the royal family have joined politicians and the armed forces at a National Service of Remembrance at the Cenotaph in central London.
The socially distanced event, which was closed off to the public because of the four-week national lockdown in England, saw The Queen, the Prince of Wales, the prime minister and the leader of the opposition, Sir Keir Starmer, all pay their respects.
Around the UK, people observed the annual two-minute silence at 11:00 GMT, with small ceremonies in Scotland, Wales and Northern Ireland taking place according to national restrictions.
