Vitali Klitschko, Mayor of Kyiv: From boxing to politics

How did the world heavyweight champion end up running a city of 3 million people in wartime?

Vitali Klitschko joins Nick from the Ukrainian capital in the midst of a Russian campaign to descimate the city's energy infrastructure.

He talks about what peace could look like, the lessons he learned from living under Soviet rule as a child, and why he decided to abandon a lucrative life in the US to enter Ukrainian politics.
