Are there any Russian spies left in Europe?

Norway detains a suspected Russian spy - the latest in a long string of expulsions and arrests. Victoria and Vitaly discuss Russian espionage with BBC security correspondent Gordon Corera. He explains how the war in Ukraine has made the job of a Russian spy in Europe harder. Also, we hear the poignant testimony of a Ukrainian soldier who is suffering from post-traumatic stress because of the fighting he witnessed. And as Russia doubles down on its claims that Ukraine is planning to use dirty bombs, we ask Chatham House’s Patricia Lewis how these bombs work and whether Russia’s allegations could lead the war to escalate. Today’s Ukrainecast was presented by Victoria Derbyshire and Vitaly Shevchenko.The series producer is Estelle Doyle. The producers are Luke Radcliff and Arsenii Sokolov.
