With bare shelves in supermarkets where tomatoes should be and some retailers rationing them along with cucumbers and peppers, we ask what's going on. Whose fault is it and is the solution turnips, indoor farms, or better contracts for farmers? In this programme we'll try to find out with a panel of experts and opinions from around the country and beyond. Charlotte Smith speaks to Kevin White, Fresh Foods Editor at The Grocer, Lee Stiles from Lea Valley Growers, Dr Kamran Mahroof, Associate Professor of Supply Chain Analytics at Bradford University, Johnathon Tremayne from Global Pacific which sources fruit and veg for supermarkets, and Ksenija Simović, Senior Policy Advisor at the European farming union, Copa Cogeca. Produced by Beatrice Fenton.
