What’s the point of the Covid inquiry?

The Covid inquiry enters its most dramatic week, questioning Martin Reynolds (a.k.a. 'Party Marty'), as well as former No. 10 advisors Lee Cain and Dominic Cummings. But it seems that the inquiry has gone down more the route of interpersonal drama rather than lessons learnt for government decisionmaking. So what's the point of it? Katy Balls talks to Isabel Hardman and James Heale. Produced by Cindy Yu.
