Interview with former undercover police officer turned crime author Stephen Bentley on the English led covert cop op that led to Loyalist Volunteer Force (LVF) killer Jim Fulton being jailed for life.
Bentley's new book Operation George takes readers inside what he describes as the "most audacious undercover police operation in the world".
He reveals how FBI pressure on UK and Northern Ireland authorities over the murder of human rights solicitor Rosemary Nelson led to Fulton talking his way into 25 years behind bars for a litany of terrorist crimes, including murder.
The former police officer also talks about his time working on one of the biggest undercover covert ops to have taken place on British soil.
Operation Julie saw a young Bentley infiltrate a Welsh LSD drugs gang during the 1970s, smashing two drug production and distribution centres, and the jailing of over 15 people for 120 years.
