 Historians have never identified the original statement referred by Völckers, Ibárruri and others.Though transcripts of Franco's, Queipo and Mola's radio addresses have been published, they did not contain the term referred; no other original statement with the phrase in question has ever surfaced.A British journalist who took part in Mola's press conference on October 28, 1936 claimed that Mola referred to "quinta columna" on this very day, though at that time the term had already been used in the Republican press for more than three weeks.
