In the midst of the coronavirus crisis, the supermarkets have become like the UK’s fourth emergency service. While most people have been staying safe in their homes, an army of workers across the country have been putting themselves at risk and working round the clock to keep us all fed. Sara Cox and Ade Adepitan have access to some of Britain’s biggest supermarkets and their suppliers to see how their systems have stood up to the most testing time in their history.
