Sinn Féin president Gerry Adams has said he does not expect a deal to restore powersharing to be struck by Monday.
He said the door was still open but there had been no sense of urgency around piecing together an agreement.
A series of deadlines have been missed to restore multi-party devolved government in Northern Ireland.
Mr Adams said: "I don't believe that there is going to be a deal by Monday.
"The DUP are showing no urgency or no real inclination to deal with the rights-based issues which are at the crux and the heart of these difficulties which we are talking here about."
He said those included republican demands for an Irish Language Act, a Bill of Rights, marriage equality and dealing with the legacy of decades of past violence.
"Unless they step-change I just cannot see, here we are on Saturday afternoon, I just cannot see how, and we told them this directly, how a deal can be put together by then."
