Sinn Féin MLA Michelle O'Neill has said political unionism must live up to the responsibility to share power.
Michelle O’Neill said:
"We have been given a very strong mandate to enter negotiations and we must now make a difference.
"The people have had their say and the message is very clear. They don’t want minorities or majorities – they want equality. They want agreements implemented. They want progressive change.
"Political unionism must now live up to its responsibility to share power on the basis of equality, to demonstrate respect and to act with integrity in government.
"From today we will start meeting with the other parties and the two governments and tell how we see it and what it'll take to fix it.
"We will confront the two governments who have shamefully undermined and failed in their duty to protect, nurture and develop the Good Friday Agreement.
"What is required is genuine power sharing and partnership with Republicans, based on equality and respect and mutual respect for our Irish national identity."
