Meanwhile, there was now a growing schism within the CNT and the FAI. Leading figures such as Horacio Prieto and minister of education Segundo Blanco argued for collaboration with the national government. Dissenting anarchists such as Jacinto Toryho, the director of Solidaridad Obrera and FAI delegate Pedro Herrera were harshly critical of this policy. Toryho was removed from his position by the CNT national committee on 7 May 1938. Two months before the fall of Catalonia, a national plenum of the libertarian socialists was held in Barcelona between 16 and 30 October 1938. Emma Goldman was in attendance and she defended the FAI in "opposition to the growing encroachment of the Negrín government on the libertarian achievements". According to José Peirats, Horacio Prieto argued for an "undisguised reformism bordering on Marxism," and that "truly effective action" was only possible through "organs of power." He also criticized the naivete of the anarchists and its "lack of concrete plans."
