The Sinn Féin President Gerry Adams says the political crisis in the North can be sorted out.
Mr Adams says his party is prepared to do whatever needs to be done to reassure people and get things back on track.
Yesterday DUP leader Peter Robinson stepped aside as First Minister, over a crisis sparked by the murder of Kevin McGuigan that police have linked to the IRA.
It has prevented the collapse of the powersharing government for now.
Sinn Féin President Gerry Adams says his party cannot help in a row between the unionist parties in the North, but Sinn Féin is prepared to do what it can to solve the current crisis.
He said: "If Mike Nesbitt decides to chance his arm as part of his battle with the DUP, I can't satisfy him, but whatever can be humanly done to reassure people, to get things back on track, we will do it.
"I said earlier and Martin McGuinness said this as well, these issues can be resolved."
UPDATE:Speaking later to a gathering of his party in Gormanstown, Co Meath, Mr Adams repeated his “grave concerns” at how he believes the political crisis has developed and been exploited.
“However, notwithstanding how the political process got to this point and how malign forces have succeeded in bringing all that has been achieved to the edge of the abyss, the collective responsibility of all the parties is to take a step back,” he said.
“We have a short window of opportunity to chart a different course through this crisis.”
