Over the years, the story of Ronald and Reginald Kray's notorious life in London's East End gang scene has been the subject of numerous entertainment and documentary television shows and movies.
ITV will be exploring the rise, reign and fall of Britain's most fearsome gangsters, beginning with their ascent to power and the influences that shaped them.
Secrets of the Krays, a three-part factual series which will air on Tuesday, January 25 at 9pm, will follow their path through protection rackets, robbery, violence and murder to their arrival as high-profile celebrities following their move into the West End in 1964.
