Democratic Unionist leader The Reverend Ian Paisley is to meet the mother of Columba McVeigh, one of a number of people abducted by the IRA and whose body has not been found.
Party sources confirmed tonight plans for a meeting which followed Mr Paisley's claim that he had been asked by recently deceased Monsignor Denis Faul to take up the disappeared's plight.
Mr Paisley recently claimed he had received the death bed plea from Monsignor Faul. The North Antrim MP said Vera McVeigh had a right to know where her son was buried.
"I know how people feel," the DUP leader said. "Here is a body. It is not buried. Somebody knows where it is. Why can't they decently hand the body back?
"Let the dear woman have it buried according to her beliefs and give her peace. Anybody that's against that should leave this country."
Columba McVeigh was 17 when he was kidnapped by the IRA in 1975 who accused him of being a spy. In 1999, the organisation finally admitted the Donaghmore man's murder.
A two-week search for his body took place along a mountainside bog on the southern side of the Irish border near Emyvale, Co Monaghan, after the IRA passed on fresh information about where his body was believed to be buried.
However the Irish Police were unable to recover the body.
At the funeral of Monsignor Denis Faul, who died aged 74 after a long battle with cancer, mourners including Sinn Fein chief negotiator Martin McGuinness, were told in Carrickmore, Co Tyrone, that the outspoken priest wanted the bodies of Northern Ireland's disappeared returned.
Bishop Gerrard Clifford, the auxiliary bishop of Armagh, said: "His plea even on his deathbed was addressed to those who had any knowledge or hint of where these bodies had been placed.
