On March 12, Mustafa Dzhemilev, a leading figure among the ethnic Crimean Tatars, had a long conversation over the phone with Vladimir Putin. No doubt, they talked about the referendum that was set to take place four days later. According to what Dzhemilev reported to the Ukrainian media, the Russian president asserted that Ukraine's 1991 Declaration of Independence, which was voted on by Parliament after a referendum, did not "comply with the Soviet procedure laid down to leave the structures of the USSR".
