Sky News and Tortoise Media are about to launch a new series looking at how British defences would be tested if the country came under Russian attack. In a unique format, they’ve assembled real-life former ministers, military chiefs, and other experts to figure out how to defend the country in that scenario. Listeners will hear the kind of wargame that is used in government. The panel will discuss how the idea came about, its development and execution – and how it hopes to push storytelling boundaries.
