Marina Litvinenko has seen a lot in her life. In 2006, her husband, the former Russian spy Alexander Litvinenko, was assassinated by radioactive poisoning by agents of the Russian government. Her unrelenting quest for justice and answers has led through the courts, the media, and the highest levels of diplomacy - and yet, after all this time, there were people in the UK who still did not heed her warnings about dealing with Vladimir Putin before last year's invasion of Ukraine. In this conversation with Robert Amsterdam, Marina discusses her campaign, views and insights on the conflict in Ukraine, and how the West should deal with punishing those around Putin (while avoiding isolation of independent Russian citizens).
