 In October 1973, David Jessel temporarily left the BBC to join commercial radio, becoming the opening presenter on LBC (London Broadcasting Company), Britain's first all-news radio station.On rejoining the BBC, Jessel moved to documentary-making, with a particular emphasis on miscarriages of justice.From 1985 he led the team at Rough Justice, the BBC's long-running investigative TV series which re-examined the cases of a dozen people convicted of serious crimes, usually murder, and led to the eventual quashing of most of the convictions.
