It is only a matter of time before DUP leader Ian Paisley does a deal to restore devolution to Northern Ireland, Sinn Fein leader Gerry Adams has said.
Gerry Adams (right) says a devolution deal is inevitable
He was speaking to party colleagues on the eve of three days of intensive negotiations at St Andrews, Scotland.
The governments have given the parties until 24 November to broker a deal.
Mr Adams said: "I do know that the question is no longer about whether the DUP will do a deal, the question is about when the DUP will do a deal."
He added: "Our responsibility therefore is to do a deal with Ian Paisley, if he can be brought to that point, and if he cannot then the process continues without him."
The DUP is refusing to speak to Sinn Fein until the party recognises and accepts the Police Service of Northern Ireland, but Mr Adams did not go into detail about his party agreeing to support the policing structures.
"Our support for policing and law and order is not a response to unionist demands. Neither is it a tradeable commodity to be retained or given away as part of a deal," he said.
Peter Hain said more talks may take place in London
Earlier, Secretary of State Peter Hain said the government was looking for a 100% deal at the St Andrews talks.
Mr Hain said no-one would benefit from a 99% agreement which "could be escaped from later".
He said he would not rule out the possibility of further talks, possibly in London.
However, he added that as a result of the St Andrews negotiations the government needed to know there was the prospect of a deal.
The talks come a week after the body monitoring paramilitary activity said the IRA had changed radically and some of its most important structures had been dismantled.
Mr Blair said the IRA's campaign was over and there was a "unique opportunity" to reach a final settlement.
The government hopes the report will help its efforts to restore devolution.
