Arundhati Roy on castes and outcasts

Booker Prize-winning novelist Arundhati Roy's latest book weaves together the lives of the misfits and outcasts from India's bustling streets. Roy is famous as an advocate for the most vulnerable and dehumanised in Indian society. She tells Andrew Marr how her main character Anjum builds a small paradise for the dispossessed in a graveyard in Delhi. Ivan Mishukov walked out of his Moscow flat aged four and spent two years living on the city streets, where he found a home among a pack of wild dogs. Playwright Hattie Naylor used this true and extraordinary story as the basis for a play and now a film, Lek and the Dogs. She explores how the human world failed to look after the child, but how his kindness won the trust and protection of street dogs.Damian Le Bas grew up surrounded by Gypsy history from his great grandmother. He sets out on the road to discover Travellers' stopping places and to understand how the romanticised stories of the past were replaced by the critical, outcast image of present-day Gypsies.The columnist and Conservative Peer Daniel Finkelstein appears to be the ultimate establishment insider. But his parents were refugees who were forced to move across Europe because of antisemitism. He believes their desire for rootedness and belonging underlines his own politics.Producer: Katy HickmanPicture: Arundhati Roy (credit Mayank Austen Soofi).
