The Caretaker Executive declared itself opposed to the ending of abstentionism, the drift towards "extreme forms of socialism", the failure of the leadership to defend the nationalist people of Belfast during the 1969 Northern Ireland riots, and the expulsion of traditional republicans by the leadership during the 1960s. The leadership faction of the party was referred to as Sinn Féin (Gardiner Place) – the offices of Sinn Féin for many years – and the other as Sinn Féin (Kevin Street), the location of the opposing offices. Both Goulding's IRA faction and Mac Stíofáin's group called themselves the IRA. At the end of 1970 then, the terms 'Official IRA' and 'Regular IRA' were introduced by the press to differentiate Goulding's 'Officials' from Mac Stíofáin's 'Provisionals'. During 1971, the rival Sinn Féins played out their conflict in the press, with the Officials referring to their rivals as the "Provisional Alliance", while the Provisionals referred to the Officials (IRA and Sinn Féin) as the "NLF" (National Liberation Front). To add to the confusion both groups continued to call their respective political organisations in the North the "Republican Clubs". With an intensification in the conflict the British government made a number of military decisions that had serious political consequences. The Falls Road Curfew would boost the "Provos" in Belfast, coupled with internment in August 1971 followed by Bloody Sunday in Derry in January 1972. These events produced an influx into the Provisionals on the military side, making them the dominant force and finally eclipsing the Officials everywhere while bringing hundreds into Ó Brádaigh's Sinn Féin. People began to flock to join the "Provos", as they were called, and in an effort to reassert its authority, the Goulding section began to call itself "Official IRA" and "Official Sinn Féin", but to no avail. Within two years the Provisionals had secured control, with the 'Officials' both North and South considered a 'discredited rump' and "regarded as a faction" by what was now the main body of the movement. Despite the dropping of the word 'provisional' at a convention of the IRA Army Council in September 1970, and becoming the dominant group, they are still known, "to the mild irritation of senior members" as Provisionals, Provos or Provies. Sinn Féin was given a concrete presence in the community when the IRA declared a ceasefire in 1975.
