RTÉ News has learned that the chairman of the decommissioning body, General John de Chastelain, will meet representatives of the Irish and British governments tomorrow to tell them that full decommissioning of IRA weapons has taken place.
General de Chastelain will present a detailed inventory of decommissioned weapons to the British and Irish governments before making the list available at a news conference.
Two independent witnesses will make a statement at the press conference to say that the promised IRA move has taken place.
It is understood the two witnesses are the Catholic priest Fr Alex Reid and Rev Harold Good, a Methodist minister.
The IRA arsenal is believed to include Soviet-built surface to air missiles, rocket launchers, heavy machine guns, armour-piercing sniper rifles, three tonnes of Semtex, about 1,000 Kalashnikov AK47 assault rifles and large quantities of handguns.
Both governments will make statements tomorrow following General de Chastelain's statement.
Sinn Féin Chief Negotiator, Martin McGuinness, has said he believes that Ireland stands on the cusp of a historic advance.
He said he was confident that tomorrow would bring the final chapter on the issue of IRA arms.
Mr McGuinness also said the IRA move will place a huge responsibility on the leadership of the DUP to re-engage in the political process and on the two governments to implement the Good Friday Agreement.
In July, The IRA called an end to its armed campaign and ordered all its units to dump arms.
It also ordered its members not to engage in any other activities of any kind.
A report confirming that the IRA has fully decommissioned all of its armaments has been submitted to the British and Irish governments on Monday (September 26, 2005).

The Chairman of the decommissioning body, General John de Chastelain met representitives of both governments, before releasing details of the report at a press conference in Belfast. A partial catalogue of the arms stock was included, as well as the statements of two independent observers present at the decommissioning process. The observers are a Catholic priest, and a Methodist minister. 

Both witnesses stressed their independence and de Chastelain commented that it was clear from their observations that the weapons had been gathered from individuals and put beyond use. De Chastelain refused to be drawn on details of the exact numbers of weapons decommissioned, the IRA having agreed to decommissioning based on confidentiality. The decommissioning panel did make comments that the weapons decommissioned did correspond with the estimates of weapons held, included a mix of new and old weapons, including surface to air missiles and heavy machine guns.

General de Chastelain, along with Andrew Sens and Tauno Nieminen, has been in Ireland overseeing this latest round of decommissioning since September. Before now, they had been allowed to witness three acts of decommissioning. However, lack of details in the reports provided afterwards meant that opponents questioned the moves.

Statements from both governments, as well as the major Northern Irish political leaders, are expected later on Monday.

The IRA announced that it was calling an end to its armed campaign in July, and ordered members not to take part in any other activities. The Unionist paramilitary UDA had withdrawn from the decommissioning after initial talks in 1999. de Chastelain indicated inventory of decommissioned weapons will not be published until full paramilitary decommissioning is complete.

===Initial reactions===
DUP MP Nigel Dodds said that decommissioning was always required for "building and instilling confidence in the unionist community", and that "it was absolutely vital to have that visual aspect."

UUP leader Sir Reg Empey said that the report needed to make clear that absolutely all arms had been put beyond use.

SDLP leader Mark Durkan said that both governments must now move forward with implementing the Good Friday Agreement.

Sinn Fein's Alex Maskey called the day "historic", commenting that the responsibility now rests with the DUP and the governments to move forward.

During the press conference, General de Chastelain faced critics who questioned the truthfulness of the process. He responded with "We have no Doubt ... We have nothing to gain by misleading you."
