Northern Ireland Deputy First Minister Martin McGuinness has said he is confident that the power-sharing administration at Stormont will not collapse, even though it faces immense challenges.
Mr McGuinness was speaking at an event in Derry to mark the 20th anniversary of the IRA ceasefire.
Sinn Féin selected an event in the hometown of Mr McGuinness to mark the ceasefire's anniversary.
He name-checked several people outside the republican movement when referring to what he called one of the momentous decisions of the last century in the politics of this island.
They included John Hume of the SDLP, the late Fr Alec Reid and the recently deceased Albert Reynolds.
His address also acknowledged the tensions in the power-sharing administration.
He was critical of what he called the unwillingness of unionists to accept democratic decisions like the one about the Union flag taken at Belfast City Council.
But he said he wants the administration to survive and told supporters there is no alternative to dialogue and agreement.
