The Green Party Leader, Mr Sargent gave what he described as a "guarded welcome" to the IRA statement on decommissioning and said he had impressed on them the need to deliver on the expectations that have been created.
Mr Sargent said that "any move on decommissioning would have to be a welcome move but that there was now a pressing need to deliver on the expectations that have been created".
"Any lack of progress will create a further political vacuum which will only weaken the Good Friday Agreement and make it more difficult to win back the confidence which is essential to building progress."
