The funeral will take place today of David Wright, father of murdered loyalist terrorist Billy Wright.
For years, he alleged that security forces and the prison service colluded in his son's murder by the INLA in the Maze prison.
Last year, an inquiry into the death of the LVF leader - who was shot dead by the INLA in the Maze in 1997 - found there was no collusion.
Mr Wright branded the report a "total whitewash and a failure to get to the truth".
He will be buried at Killicomaine Baptist Church in his home town of Portadown.
