A new biography of Mahatma Gandhi called Mohandas - A true story of a man, his people, and an empire, written by his grandson Rajmohan Gandhi released in New Delhi by UPA Chairperson Sonia Gandhi. But what's the new thing about this biography? It's no one has written extensively and deeply about Gandhi's personal life. The biggest question is who is Sarla Devi Choudhary in Mahatma Gandhi's life? Was he having an extramarital affair with her?
