The war crimes investigator

Nigel Povoas is a British lawyer who travelled to the newly recaptured territory in Eastern Ukraine as part of an international team helping with war crimes. He tells Victoria and Vitaly why based on his experience of the war so far, he believes more evidence of atrocities will emerge.

They also talk to Volodymyr Zelensky, who is from the city of Izyum, where a mass burial site has been discovered. He describes life under Russian occupation and the risks associated with sharing the same name as the Ukrainian president.

Also, they’re joined by the BBC Russia’s Olga Ivshina. Together they discuss the significance of leaked footage showing the head of the Russian mercenary company, the Wagner group, telling prisoners they would be freed if they served six months in Ukraine.

And we hear from Pavel Filatiev, a Russian soldier who fought in Ukraine, but has now become an outspoken critic of the war.
