The Rev Ian Paisley yesterday stepped up his condemnation of republicans over their stance on decommissioning.
Victims of IRA violence deserved a public demonstration of illegal weapons being put beyond use, the DUP leader said. He further accused the IRA of deceit, saying its members wanted to retain their weapons.
Dr Paisley challenged the IRA of never having "any intention of decommissioning".
Neither had the IRA acted honestly or honourably "by allowing the people who have been humiliated by decades of IRA violence to see that their weapons are destroyed once and for all.
"The IRA celebrated their violence in the most public way possible. It is only right that those once terrorised are satisfied in a convincing way that terrorism by the IRA is no more."
He said putting weapons beyond use using the same methods as before would be unacceptable. "Another secret act of decommissioning will not satisfy the public to any acceptable degree. I believe the IRA's reaction is proof that they cannot and will not be honest about the matter of decommissioning, and are, therefore, not ready for the democratic process."
He said Mr Tony Blair should move ahead on pledges to form a new powersharing administration containing only parties committed to constitutional politics.
Earlier, Mr Jeffrey Donaldson said he hoped republicans would take time to reflect on the progress that had been made in the negotiations.
"Republicans need to set themselves some serious questions about what has happened," said the DUP Lagan Valley MP. "If there is going to be an impasse over decommissioning, then it could go on for a long time."
As the fallout from Wednesday's events deepened, the SDLP criticised the Government of compromising constitutional nationalism.
Mr Mark Durkan said the British-Irish blueprint for a restored Stormont was vague and unacceptable as it marked too much of a departure from the Belfast Agreement.
"What I absolutely resent is when the Irish national democratic interest is compromised, and when people pretend that there have not been changes to the agreement and worse yet to come."
Speaking at his party's Belfast headquarters yesterday, Mr Durkan said the DUP had won vetoes over nationalist ministers which it would use repeatedly.
Turning to republicans, he said: "Sinn Féin's priority has been about the self-image of the IRA, not the proper democratic interests of the nationalist people. The more we read of this document, the more we are confirmed in our view that this is not a complete agreement."
The SDLP welcomed IRA declarations on ending paramilitary activity and signing on to the new beginning to policing, and DUP commitments to powersharing.
"We want to ensure that nothing we do in the coming weeks releases theses parties from these commitments. We want to preserve all that is good in the document.
"But this is not a complete agreement. A lot of things that we were told would be bolted down are not. We have serious issues about the DUP's commitment to devolution of justice and when Sinn Féin will sign on for policing.
"Above all, we have concerns that the DUP has won new vetoes over not just the appointment of nationalist ministers but their decisions too."
Because Sinn Féin "has focused on photos" the party had handed "new vetoes" to the DUP.
"Sinn Féin does not appear at all concerned with how the DUP can use these changes and vetoes to humiliate nationalists and nationalist ministers in the future."
He said neither he nor any nationalist could trust the British government to stop at the changes in yesterday's document.
"We will not be doing anything to jeopardise any positive prospects.
"But we will not forfeit our right to stand by and stand for the Good Friday agreement whilst others are selling it short."
