Labour Party leader Pat Rabbitte said the IRA’s statement on Robert McCartney was welcome if it truly removed obstacles to the murder investigation.
Mr Rabbitte said it appeared, if taken at face value, to be a significant step forward in the traditional approach to co-operation with the criminal justice system in general and the police service in Northern Ireland in particular.
The Dublin South West TD added: “In the longer term the real test of the IRA’s bone fides will be whether or not they are prepared to release communities in Northern Ireland from the thuggish hold they have exerted over them for far too long.
“The McCartney family have made it clear that they want people to co-operate with that investigation. They have complained that republicans were pressuring witnesses not to talk to the police.
“It seems that the IRA may at last have been forced to listen to the voice of a family from the heart of their own community and to those who stood with them in solidarity.”
