In 2012 Mark's TV programme "Exposure: The Other Side of Jimmy Savile" exposed Savile as a prolific paedophile and predatory sex offender. Savile sexually abused hundreds of victims, many when they were children, and is considered by police to be the most prolific paedophile in British history.
Nazir and Mark discuss the challenges Mark faced in breaking the Savile story, Nazir's successful prosecution of the Rochdale child sex abuse ring and the effect that both cases have had on safeguarding and policing policies since.
