A galaxy of political leaders led by British Prime Minister David Cameron and Finance Minister Arun Jaitley were joined by Bollywood legend Amitabh Bachchan and the Mahatma Gandhi's grandson Gopalkrishna Gandhi at the ceremony to unveil the 9-foot statue of India's Father of the Nation.
Gandhi is the first Indian and the only person never to have been in a public office to be honoured with a statue at the Square.
"This statue is a magnificent tribute to one of the most towering figures in the history of world politics and by putting Mahatma Gandhi in this famous Square we are giving him an eternal home in our country," said Cameron.
Quoting some of Gandhi's famous words, Cameron highlighted how his teachings remain as potent today.

"This statue celebrates the incredibly special friendship between the world's oldest democracy and its largest, as well as the universal power of Gandhi's message," Cameron said.
Jaitley, invited to the UK especially for the unveiling, said the statue was a tribute to the British sense of civility that they now choose to honour someone who was conventionally regarded as their adversary.
"It is a great tribute to both British liberalism and British democracy that they have now chosen Gandhi to share what is the most prominent public space in this country. It is a great day when two adversaries and contrarian viewpoints converge to appreciate each other," Jaitley said.
