Solakov's second letter to Todor Zhivkov regarding accusations against him, expressed at a CC BCP Politburo meeting in July 1971. The accusations caused the removal of Solakov as a Minister of the Interior, and his removal as a CC BCP member. According to Gen. Solakov, he made a mistake of not informing Todor Zhivkov about few rumors. The first one was that he presumably intended to make a Party career with a promotion to the position of CC BCP Secretary. The second was connected with a circulated inside CC BCP compromising information that Solakov allowed the US CIA to receive through the Bulgarian company TEXIM (a cover KDS organization for arms transfer in Third World countries) several million dollars in an Arabic country.
