The Queen, Duke of Edinburgh, Prince Harry and Prince Williams were among senior Royals who laid wreaths at the Cenotaph in Whitehall to mark Remembrance Sunday.
Prime Minister David Cameron, Deputy Prime Minister Nick Clegg and Labour leader Ed Miliband were also among politicians and dignitaries who laid a wreath to honour British service personnel who have died during conflict.
It followed a two-minute silence that was observed at 11am.
Britons joined in silence to honour those who made the ultimate sacrifice at services across the United Kingdom and abroad.
Millions across the UK fell silent in tribute to those lost in war, standing in a moment of quiet contemplation as history was remembered.
