In September 2005, a number of cumainn (or branches) and individual members of RSF left the party in protest over the party's treatment of Continuity IRA prisoners held in Portlaoise Prison.
In August 2010 it was reported that members of the Limerick cumann were expelled, and had first adopted the name Limerick Independent Republican Organisation, before changing it to Real Sinn Féin, then simply Republican Sinn Féin, and finally Continuity Sinn Féin [REF].
