The Russian President’s aide Vladislav Surkov, who was responsible for the Russian annexation of Crimea, collected data about the peculiarities of the electoral system of Crimea as early as in 2013.
This follows from Surkov’s correspondence published by hackers.
So, on November 29, 2013 he received information about the electoral system of Crimea and Sevastopol, indicating the number of voters and the turnout during the last parliamentary elections. It is quite possible that this information was analyzed to prepare the so-called “referendum” on the status of Crimea.
We remind that on the same November 29, 2013 in Kyiv, “Berkut” (a former law enforcement unit) militiamen destroyed a tent camp of supporters of European integration — activists and students. This incident caused the massive wave of protests in Ukraine.
