The files relating to the criminal lawsuit involving the Russian businessmen Oleg Deripaska and Iskander Makhmudov arrived in Moscow after the case was first processed by the Spanish authorities, Interfax’s informed sources report.

‘This is a rather bulky dossier comprising tens of volumes, which is why it took over a month to have the files delivered from Spain to Russia,’ a source familiar with the case told the agency.

According to this informant, the files arrived in Russia at the end of December 2011.
