Last November we were joined in the studio by Ukrainian journalist and writer, Mstyslav Chernov, who made the film '20 Days in Mariupol’. It’s just won the Oscar for Best Documentary feature, so we thought it would be a good opportunity to remind you of the episode. He described what it was like to shoot the documentary from inside Mariupol, and chronicles the Russian invasion of the Ukrainian port city in 2022. Today’s episode is presented by Victoria Derbyshire and Vitaly Shevchenko. The technical producer was Mike Regaard. The series producer is Tim Walklate. The senior news editor is Sam Bonham.
