According to Erindzher, Sotrama was part of oil trade network set up all across Europe by the Russian leader and his confidants. The aim of this network’s existence was to assist in money laundering of funds embezzled from the federal budged through investments in real estate in Europe.
According to a Spanish lawyer, Pablo Sebastian, Skigin knew Vladimir Putin who, being chairman of the St. Petersburg City Hall Committee on External Relations, registered a number of companies owned by Skigin. According to Erindzher, Putin was linked not only to Sotrama but also to a network of similar companies in Europe. The police documents also mention the name of Gennady Timchenko, a good friend of Vladimir Putin and co-owner of Gunvor, a company dealing in export of Russian oil.
