Strongmen – what accounts for the global rise of authoritarian leaders? Laurie Taylor talks to Ruth Ben-Ghiat, Professor of History and Italian Studies at New York University, and analyst of the blueprint which autocratic demagogues, from Mussolini to Putin, have followed over the past 100 years. What lessons might be learned to prevent disastrous rule in the future? They're joined by Christophe Jaffrelot, Professor of Indian Politics and Sociology at King's College, London, whose recent study of Narendra Modi, Prime Minister of India, examines how a popularly elected leader has pursued Hindu nationalist policies, steering the world's largest democracy towards further ethnic strife and intolerance, according to many observers.
