Russia's central bank hiked interest rates to 20% as the rouble's value plunged up to 30%. We bring you up to speed with all the latest sanctions that have been imposed on Russia as a result of its invasion of Ukraine, and we explore their potential long-term impact with Adnan Vatansever of King's College, London, who is an expert on the Russian economy. Also in the programme, we hear from Olga Shapoval, who is executive director of the city of Kharkiv's IT cluster, in northeastern Ukraine. And we get an update from Oleg Chernyak of the software development company CHI Software, who we've been speaking to since the crisis in Ukraine began, and is now in the Carpathian mountains in the west of the country. Plus, as Germany reviews its energy policy with a view to moving away from a heavy reliance on Russian gas, we find out more from Jakob Schlandt who is an energy expert at the German paper Tagesspiegel.
