Gerry Adams rules out chances of deal by Monday
Sinn Fein President Gerry Adams said a deal to restore power-sharing in Northern Ireland by the new deadline, is "highly unlikely."
The most recent deadline was extended over the weekend after politicians failed to secure an agreement on Thursday.
Secretary of State James Brokenshire is due to address the House of Commons on Monday, to advise on the way forward.
Speaking at a same sex marriage rally in Belfast on Saturday afternoon, Gerry Adams accused the DUP of digging their heels in:
"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."
