The leadership of the Loyalist Volunteer Force has ordered all its military units to stand down.
The move, which takes effect from midnight, is a direct response to the IRA's decision to decommission its weapons arsenal.
It also followed a formal end to the feud between the LVF and the rival Ulster Volunteer Force.
That development came following the intervention of a group of church and community activists from Belfast and Portadown who have been involved in discussions over several weeks.
Tension between the LVF and UVF had been ongoing and had occasionally erupted into violence.
In July and August this year, a new phase in the feud began when the UVF shot dead four people.
The DUP's Nigel Dodds welcomed the news but said it came too late for the bereaved families.
He paid tribute to those who have worked so hard to bring 'this resolution about'.
It is thought that next week the LVF will announce that it is disbanding and decommissioning its weapons.
The LVF was formed in the mid 1990s by the notorious Portadown loyalist, Billy Wright, who was later shot dead in the Maze Prison.
