Sinn Féin President Gerry Adams has denied allegations that he was involved in the disappearance of mother-of-ten Jean McConville in 1972.
A book based on interviews with a former IRA leader, Brendan Hughes, who died in 2008, claims Mr Adams ordered the murder of Mrs McConville over claims she was a British army informer.
She was taken from the Divis Flats on the Falls Road in Belfast and shot by the IRA. She was buried in an unmarked grave in Co Louth that was only discovered in 2003.
Mr Adams said: 'I reject absolutely any accusation that I had any hand or part in the killing and disappearing of Jean McConville or in any of the other allegations that are being promoted.
'The issue of the disappeared is a terrible legacy of the conflict. A grievous wrong has been done to these families.
'Republicans working with the Commission have being trying to right this wrong for some years.
'The proposal to do this was initiated by me after I was approached by some of the families involved.'
Mrs McConville's daughter says she intends to take legal action against Mr Adams over his alleged role in her mother's disappearance.
Helen McKendry said she would pursue Mr Adams through the courts in an attempt to get the real truth of what happened to her mother.
'Voices from the Grave' was written by journalist Ed Moloney, who interviewed Mr Hughes on several occasions before his death.
