Mark Urban at Edinburgh International Book Festival

TALL SPIRES, TALL TALES The Salisbury poisoning of Sergei Skripal was one of the strangest stories of 2018. The Kremlin’s presumed involvement turned the case into a circus, but broadcaster Mark Urban has solid evidence, drawn from interviews Skripal gave pre-attack. The Skripal Files investigates his time in the Russian intelligence services and recruitment by MI6, starting a chain of events that would bring him close to death and worsen already fragile UK-Russian relations. Chaired by Ruth Wishart
