On this edition of the Sky News Daily podcast with Jonathan Samuels, we look in detail at dexamethasone - the drug being described as a "remarkable breakthrough" in the treatment of coronavirus. We are joined by Dr Joe Grove, a virologist at the Institute of Immunity and Transplantation at UCL, and Dr Ria Lina, a comedian and specialist in viral bioinformatics. Plus, we examine whether George Floyd's death will lead to lasting change on racial injustice, as part of our special programme 'Race And Revolution: Is Change Going To Come?'Credits:Producer – Kit BradshawAssistant producer – Sabah ChoudhryInterviews producer – Oli Foster
