The important person in this process was de Prado, who was assisted by Zamanillo. In 1973 the Comisión Permanente of Junta Nacional de Jefes de Requetés, led by de Prado, issued a manifesto which declared Don Carlos Hugo to be a traitor to the sacred cause. In 1975, de Prado and his followers pledged loyalty to Don Sixto. His group, Jefatura Nacional de Requetés, continued to issue manifestos and may have been involved in the Montejurra shooting in 1976.
