A 36-year-old Portadown man has gone on trial at Belfast Crown Court accused of 64 charges relating to LVF terrorist activity over an eight-year period.
The court heard that William James Fulton, of Queen's Walk, denied the charges, which include three murders and nine attempted murders.
Three co-accused also deny charges relating to terrorist activity.
A Crown lawyer alleged that the defendants had been secretly recorded confessing to an undercover detective.
Mr Fulton is accused of murdering Elizabeth O'Neill, Catholic council worker Adrian Lamph and Catholic taxi driver Michael McGoldrick.
Muriel Gibson, 55, from Clos Trevithick, Cambourne in Cornwall, denied a total of 11 charges including the murder Mr Lamph, possessing guns and explosives, membership of the LVF and withholding information.
Her two daughters Rain Landry, 28, of the same address denies charges relating to explosives, arson and having a petrol bomb, while Talutha Landry, 31, from Penrose Park in Portleven, Cornwall, denies two charges relating to firearms.
All of the charges against the four are alleged to have taken place between 14 December 1991 and 30 September 1999.
During police questioning both Mr Fulton and Ms Gibson claimed they had been "bragging" in an effort to impress the undercover police officers.
The trial continues.
