Shaun Ley speaks to Andriy Kobolyev, CEO of Ukaine’s Naftogaz. Ukraine is a country at war with itself, and not just because of separatists in the east. Corruption is endemic, especially in state industries. Andriy Kobolyev, CEO of state-run energy company Naftogaz is trying to clean it up. He wants to make gas more expensive, because massive subsidies discourage investment and encourage waste. But energy scams are a big source of income for some powerful people. Are his efforts being sabotaged from the very top?(Photo: Head of Ukrainian Naftogaz state oil and gas firm Andriy Kobolev walks in front of the company's logo, 2014.
