A peal of bells marked 50 years since Martin Luther King delivered his historic I Have A Dream speech in London's Trafalgar Square at 3pm this afternoon.
Across the world today nations are paying tribute to the black civil rights leader who urged the world to "let freedom ring" as he addressed a rally of 200,000 people in Washington in 1963.
Dozens of young people took part in the Trafalgar Square event as part of The Dream Series, Director Natalie Wade said:
"Fifty years on and it's hard not to be inspired by the Martin Luther King speech and the March on Washington."
Tens of thousands of Americans have gathered in Washington to mark 50 years since Martin Luther King made his I Have a Dream speech.
Today marks 50 years since Martin Luther King's famous I Have a Dream speech - but how far has America come in realising that dream?
