A CONVICTED killer has denied knowledge of two voicemails allegedly sent by another man who is accused of plotting to murder two former high profile loyalist terrorists.

Antoin Duffy is in the dock at the High Court in Glasgow accused of plotting to kill Johnny "Mad Dog" Adair and Sam McCrory, formerly senior members of the Ulster Defence Association and its military wing the Ulster Freedom Fighters.

Scott Paton, 41, who is serving life in prison for murder and cannot apply for parole until 2023, told the court he could not remember ever receiving the voicemails from Mr Duffy.

When asked by prosecutor Paul Kearney: "What does "the big fella" mean," Paton replied: "Not got a clue. You would have to ask him."

Earlier, Edward McVeigh, who shared a cell with Mr Duffy, claimed that his fellow inmate planned to shoot Adair with an assault rifle he called "the big fella".

Paton, 41, met him in Addiewell Prison in West Lothian and they became friends after training together in the gym. Mr Duffy later painted a picture for Paton and after he left to go to Castle Huntly open prison, they kept in contact by letter and phone.

Paton told the court that he also was in Addiewell with Gary Convery, who is accused of involvement in organised crime, but could not remember exactly when.

Mr Duffy, 39, Martin Hughes, 36, Paul Sands, 31 and John Gorman, 58 , deny conspiring to murder Adair and McCrory.

Mr Duffy and Mr Gorman have also pleaded not guilty to involvement in a plan to murder the governor of Barlinnie jail with a car bomb.

Mr Convery, 37, Gary Convery, 34, and Gordon Brown, 29, deny organised crime charges.

The trial before Lady Scott continues.
