London Mayor Ken Livingstone wants a statue of Mahatma Gandhi in Parliament Square, London.
Speaking to BBC, he said India was part of British history and Gandhi's achievement must be enshrined.
Former South African leader Nelson Mandela's statue was unveiled in Parliament Square last month.
Livingstone said: "If you're looking for people who represent a major part of our history, which South Africa is, or you think of India, I wonder whether or not we shouldn't be looking at having a statue of Mahatma Gandhi, who perhaps had a bigger significance on the British Empire than anyone else, because two thirds of it got independent overnight.
"You get millions of people from all over the world who come to see Big Ben and see the statue of Churchill and so on, and here's someone they would understand.
"In a thousand years they'll still know who Mahatma Gandhi was, whereas if you wander round Trafalgar Square, the two generals there, you have to go and check the history books."
