David Olusoga talks to Kirsty Lang

Hay Festival’s annual lecture celebrates the issues central to the late George Alagiah’s work: migration, the power of the global majority and questions of representation. This year, British-Nigerian historian, author, presenter and BAFTA-winning film-maker David Olusoga discusses the history and legacy of the British Empire and how colonial nostalgia is shaping contemporary geopolitics, with journalist Kirsty Lang.
