In 1979, Panorama reporter Tom Mangold led an investigation into the trial of Jeremy Thorpe and others, for the alleged conspiracy to kill Thorpe's former lover, Norman Scott. Convinced that the former Liberal Party leader would be found guilty, a special post-trial programme was prepared - but scrapped when the jury returned its verdicts of not guilty for all defendants. This programme has remained unseen for almost 40 years. Edited and updated with new information about a fresh 2017 police inquiry into the case, Tom Mangold finally presents his story about how powerful political forces tried to protect Thorpe. Featuring revealing interviews from 1979 with Norman Scott, chief prosecution witness Peter Bessell, and the so-called 'hitman', Andrew 'Gino' Newton
