President Putin's Commissioner for Children's Rights

Will the collapse of the UN grain deal and attack on port cities in Ukraine affect food security?

James Waterhouse joins us from a grain processing plant in Poltava and we also hear from Oksana Karabin, who works for Ukraine's biggest grain exporter Kernel. Their terminal was shelled this week destroying 60 tonnes of grain.

And we return to the issue of the forced deportation of Ukrainian children by Russia. We hear from Vice correspondent Isobel Yeung and the BBC’s Kateryna Khinkulova - two journalists who’ve been investigating the story for several months.

Today’s episode is presented by Lucy Hockings and Lyse Doucet.

The producers were Arsenii Sokolov, Clare Williamson and Tom Smithard. The technical producer was Rohan Madison. The series producer is Tim Walklate. The senior news editor is Sam Bonham.
