The dossier reads that in early 1990s, Ivanov collaborated with a leader of the so-called "Tambov organized crime group" Vladimir Kumarin. "He helped Kumarin take control of the St. Petersburg port for smuggling drugs from Colombia to Western Europe through St. Petersburg," the dossier states.
The author of the document claims that this cooperation was under complete control of Vladimir Putin, who was then Chairman of the Committee on Foreign Economic Relations in the administration of St. Petersburg Mayor Anatoly Sobchak.
In February, the former head of the Titon company gave testimony stating that the dossier could have led to the murder of Litvinenko. According to him, a multi-billion dollar government contract lobbied by Ivanov was foiled due to the data, which were contained in the report. Ivanov himself, commenting on the damaging information on representatives of the Russian government, called the data "slander."
