Professor George Gao, the former head of China's Centre for Disease Control (CDC) recently told the BBC that no theory for the origins of the COVID-19 pandemic should be ruled out including whether or not it came from a lab, after years of extremely insistent public denials from the Chinese leadership. Gao added that China investigated whether the virus may have originated from the Wuhan Institute of Virology and admitted that he hadn't actually seen the results of the investigation, but heard that the Institute had been cleared. One Decision's Julia Macfarlane speaks with co-host and former MI6 Chief Sir Richard Dearlove about why China is speaking about the origins of the virus now, why he thinks it has zoonotic origins, and why he concluded there's a strong probability it was leaked from the Wuhan lab.
