An interview with an IRA member who alleges Gerry Adams was involved in the murder of a west Belfast woman has been broadcast for the first time.
Mother-of-ten Jean McConville disappeared from her home in 1972. She was killed and secretly buried on a beach in County Louth.
The interview was conducted with Brendan Hughes in 2008 and was broadcast on RTE on Tuesday evening.
Mr Adams has denied being involved in Mrs McConville's disappearance.
Brendan Hughes' account of his life in the IRA has already been published in a book, Voices from the Grave.
On a tape, he claims the IRA twice found a British army radio transmitter in Mrs McConville's home in Divis flats.
He adds that she ignored a warning and that led to her murder - which he later regretted.
He says: "A special squad was brought into the operation then, called The Unknowns.
"Anyone that needed to be taken away, they normally done (sic) it. I had no control over this squad. Gerry had control of this particular squad."
The McConville family has denied their mother was an informer. That was later backed up by an Ombudsman's report.
