Lawyers for John Gilligan will continue their cross-examination of state supergrass Russell Warren at the Special Criminal Court this morning.
Warren claims he witnessed the murder of Veronica Guerin and was ordered by Gilligan and convicted murderer Brian Meehan to follow the crime journalist from Naas on the fatal day.
He also alleges Gilligan threatened to kill him a number of times before and after the murder, if he told anyone about it.
