In the first episode of our second series of Resurgence Voices, Satish describes how heroes have influenced his own journey. His 8,000-mile walk for peace in the 1960s started from the grave of Mahatma Gandhi and took him to Atlanta Georgia, where he met Martin Luther King.

But the heroes of today have a very different challenge to face. “I think the next revolution will be led by a younger person, by a woman, and I feel that Greta Thunberg is that person,” Satish says. “I think that some kind of divine power but also some kind of unseen, unimaginable, unexplainable force is working through her.”

What does Greta think of that? Amid a scrum of journalists at the Mayflower Marina in Plymouth, I get a chance to ask her.
