As efforts continue to reach a political deal in the North, Sinn Féin is to hold ground-breaking talks with the North's Chief Constable in Downing Street tomorrow.
This will be the first face-to-face meeting between Sinn Fein's leadership and Huge Orde.
Sinn Féin's Gerry Adams said tonight the discussions with Hugh Orde would focus on an accelerated programme of scaling down fortifications in the event of a peace deal.
Bush discusses NI peace deal with Adams
Earlier, Mr Adams received a call from the US President, George W Bush, as Sinn Féin and the DUP work towards an agreement.
Mr Bush had spoken to the DUP leader Ian Paisley on Friday as the parties prepared their responses to the latest proposals on a power-sharing formula from the British and Irish governments.
Mr Adams said he thanked Mr Bush for his interest and he briefed him on Sinn Féin's two objectives in the current negotiations.
These were, he said, to get the DUP on board for an agreement and to ensure the British government position remained faithful to the provisions of the Good Friday Agreement regarding power-sharing, equality based and all-Ireland institutions.
Mr Adams said he told Mr Bush they might need the help of the White House to deliver these requirements.
The Sinn Féin leader said that Irish America, the Bush administration and the previous Clinton administration had been very helpful throughout the peace process, he said.
Mr Adams said his party looked forward to a continuation of the positive involvement of the United States in the peace process in Ireland.
Tomorrow, a DUP delegation, led by the Reverend Ian Paisley, is to meet the man who oversees weapons decommissioning in the North, General John De Chastelain.
