Publishers abandoning authors. Galleries removing paintings. Universities banning speakers. Cancel culture seems to be all around us. But if decent discourse is dying, how can we maintain the antiquated virtue of tolerance? Speakers include David Olusoga, historian and broadcaster; Shazia Mirza, comedian and writer; Sarfraz Manzoor, author, broadcaster and screenwriter; and Sir Jonathan Bate, author, broadcaster, academic. Chaired by Alan Rusbridger, Editor of Prospect Magazine.
