Now with Empireworld he traces the legacies of the British Empire across the globe exploring how 2.6 billion people live in former British colonies. His journey takes him from Barbados and Mauritius to India, Nigeria and beyond, demonstrating just how deeply British imperialism is baked into our world. And why it’s time Britain was finally honest with itself about empire. In conversation with historian and BBC broadcaster Kavita Puri. £14.
