The most diabolical TV moments. Classic compilations include politicians such as Michael Heseltine and Kenneth Clarke stomping out of interviews, presenters David Dimbleby and Tracy MacLeod left high and dry on live television, and confessions from some top executives, producers and celebrities, including Michael Grade , Sir Denis Forman , Mark Shivas, Joan Bakewell and Humphrey Burton , who reveal their famous blunders. And there are gentle postmortems of legendary programmes such as The Borgias, Churchill's People, Triangle and Sin on Saturday.
