The family of Brian Stack, the prison officer who died after he was shot by the IRA 30 years ago, met with the Taoiseach Enda Kenny today and said they were happy with how it progressed.
Tánaiste and Minister for Justice Frances Fitzgerald was also at the meeting.
The family said they were pleased with the discussion and said they got assurances that the gardaí would receive all the resources necessary for their investigation into the murder of Mr Stack and that there would be no political interference.
They also said they were expecting the Taoiseach or the Tánaiste to revert to them in a timely fashion in relation to other confidential matters.
Mr Stack's widow Sheila and her two sons Austin and Oliver met with Mr Kenny and Ms Fitzgerald at Government Buildings.
The family has described as "scandalous" the fact that Sinn Féin leader Gerry Adams has not yet been questioned by the gardaí investigating the murder.
They have called on Mr Adams to give gardaí the name of a man who told them over three years ago that IRA members had killed their father.
In a statement this evening, Mr Adams said that the investigation into Mr Stack's murder is a "live garda investigation" and that he is prepared to co-operate with the gardaí.

In 2013, Austin and Oliver Stack were driven in a blacked-out van with Mr Adams to an unknown location for a meeting with an IRA man.
Mr Kenny has said that the Sinn Féin leader should tell all he knows but Mr Adams has insisted he has no information on the murder.
Mr Stack was chief officer in charge of security at Portlaoise Prison when he was shot in the back of the neck in 1983. He died 18 months later.
The family said that Mr Adams has information that is crucial to that investigation.
They say the man they met in 2013 told them the IRA was involved in Mr Stack's murder but it was not sanctioned and they now want Mr Adams to give that man's name to the gardaí.
Mr Kenny supports the family's call but Mr Adams has said on a number of occasions he has no information on the killing.
He also stated this in an email to the Garda Commissioner in which he also named four people in relation to the case.
Two were later identified under Dáil privilege as Sinn Féin TDs, Dessie Ellis and Martin Ferris.
Both deputies also denied they had information on the murder.
The Stack family today said their father did the State some service and is owed a fully resourced inquiry into his murder.
