World Business Report: grain special

In this in-depth special programme, we look at the continuing impact to the world's food supply of the ongoing conflict in Ukraine. Despite the fact a grain deal was brokered by Turkey six months ago, 13 million people are still facing severe hunger according to Unicef. We speak to Unicef's Deputy Regional Director for Eastern and Southern Africa, Rania Dagash about this. Ukraine's Deputy Infrastructure Minister Yurii Vaskov explains how it's far from simple getting grain ships to leave the war-torn country, which is one of the world's largest producers. Bilal Muftuoglu, agricultural specialist at Argus, gives us a full analysis of global grain prices across this year - and provides a forecast for 2023.
