the CGT-Azopardo José Ignacio Rucci); and the CGTA (CGT de los Argentinos), a more radical union headed by Ongaro. The CGTA, which also included the Córdoba Light and Power Workers' leader Agustín Tosco, played a key role in the Cordobazo student-labor uprising of 1969, during which it called for a general strike. The military junta then jailed most of the CGTA leadership, who were close to left-wing causes such as the Movement of Priests for the Third World, Liberation Theology, and the Grupo Cine Liberación film movement. Following the failure of a 120-day strike at the Fabril Financiera industrial conglomerate, and the reconciliation between Augusto Vandor – leader of the "participationists" – and Perón, the CGTA witnessed many of its unions joining the "62 Organizations," the Peronist political front of the CGT. Perón and his delegate, Jorge Paladino, followed a cautious line of opposition to the military junta, criticizing with moderation the neoliberal policies of the junta but waiting for discontent inside the government. Despite this, in 1969 the CGTA still boasted 286,184 members; while the Nueva Corriente de Opinión (or Participationism), headed by José Alonso and Construction Union leader Rogelio Coria, boasted 596,863 members; and the CGT Azopardo, headed by Vandor, boasted 770,085 members and the majority in the Confederal Congress. Assassinations of the leadership and conflict with the far left The 1969 assassination of UOM Secretary General Augusto Vandor, and that of the CGT Secretary General, José Alonso, in 1970, created a power vacuum that left Vandor's conservative successor at the UOM, Lorenzo Miguel, at the CGT's leading power-broker. He leveraged his influence to advance a rival within the UOM, José Ignacio Rucci, as the new Secretary General of the CGT. The pragmatic Miguel thus turned a rival into an ally, while impeding the more combative Light and Power workers' leader, Agustín Tosco, from rising to the powerful post. Rucci maintained good relations with the dictatorship and earned the aging Perón's friendship. The next years were blemished by often bloody internal disputes and the fight against the leftist Montoneros, however, and in September 1973, a commando killed Secretary-General Rucci. The Montoneros, who neither claimed responsibility nor denied it, were accused of Rucci's death, and the event triggered an escalating conflict between left and right-wing Peronists spearheaded by the Montoneros and the Argentine Anticommunist Alliance, respectively. Other CGT leaders killed by leftists include Machine and Autoworkers Union head Dirk
