Democracy rests on a vision of social change and human development, and visions need aspiration and hope to materialise. While we live in a time of social discontent with how democracy and governance work, we are witnessing the explosion of a multiplicity of civil society movements worldwide. Discussing the future of democracy and the relationship between hope and democratic politics are: Lyse Doucet, BBC's Chief International Correspondent, historian and broadcaster David Olusoga, and Sarah Churchwell, Professor of American Literature and Public Understanding of the Humanities at the University of London.
