The African National Congress, the 'party of Nelson Mandela', is in crisis after corruption allegations against its leader and South Africa's president Jacob Zuma. At the same time, protest movements have grown up around the country, often led by young people fighting against symbols of the racist past and questioning the direction the Rainbow Nation is headed. In This Week's World, we report on the 'born free' generation across South Africa and Emily Maitlis interviews ANC treasurer General Zweli Mkhize and other leading political figures from the country. We also feature an interview with Amartya Sen, the Nobel Prize-winning economist, reflecting on poverty and national identity in his native India and elsewhere.
