Sinn Féin is calling for another Assembly election after Friday.
The party's leader at Stormont said there is little prospect of agreement in the current round of talks to save devolution.
Michelle O'Neill believes the electorate in Northern Ireland should have their say.
"We remain committed to trying to deal with the issues which are there," she said on Monday.
"We have set out what we need to see delivery on and we need to see a different approach from the DUP and, indeed, from the British Government.
"But post-Friday, I think it is over to the electorate to have their say about the future.
"But clearly Sinn Féin want to make these institutions work, but they have to work for all our citizens."
Secretary of State James Brokenshire has given the politicians until 8 April to strike a deal but the deadline is for all intents and purposes Friday.
If there is no agreement he has said he will consider the way forward over Easter.
