Roger Cook (journalist) - Checkpoint

In 1971 he created and presented the Radio 4 programme Checkpoint, which specialised in investigating and exposing criminals, con-men, injustice and official incompetence - and then confronting the wrong-doers on tape. He is credited with creating a new genre of investigative reporting. One 1979 programme about notorious rock manager Don Arden proved to be a colourful encounter. 'When you fight the champion you go 15 rounds, you've got to be prepared to go the whole way,' Arden tells Cook: 'I'll take you with one hand strapped up my arse. You're not a man, you're a creep. You’ll be served with a writ shortly. If you want to dig up dirt about me, I’ll take your last five pounds for doing it.' The promised legal action never happened and Arden's career subsequently went into decline.
