On When It Hits the Fan, we often talk about crises as if they should be avoided at all costs. But Dorothy Byrne, the former head of News and Current Affairs at Channel 4, is living proof that walking towards the fan is often a hallmark of people that effect positive change.

In this special deep-dive interview, David Yelland and Simon Lewis talk to Dorothy about the relationship between PR and journalism, being lobbied, and her fearless approach to reporting the truth – including her 2019 MacTaggart lecture when she called the then prime minister a “known liar”.
