Sinn Fein negotiator Martin McGuinness claimed today police in Northern Ireland are using the murder of Robert McCartney as a tool to politically damage the party.
He says the PSNI was in a position to charge people for the killing, but was choosing not to do so.
Speaking to Sky News, Mr McGuinness said republicans and the IRA have no problem with providing any information they have on the murder.
He denied claims by the McCartney sisters that witnesses are afraid to come forward with evidence.
Meanwhile, the family of Robert McCartney say they have learned that two of those directly responsible for his murder are willing to confess, if they can claim they were acting on orders.
Speaking to the Sunday Independent, Catherine McCartney says the wall of silence in the Republican community would collapse if the Provisional movement were to deliver one of its senior members, who ordered the assault on Robert.
