"We provide summary information on the number of voters who received ballots at polling stations (voter turnout) in the local elections on October 25, 2020. The summary comprises the data according to all TECs that were to provide such information at the close of voting in the Ukrainian regions."
To recap, this information is not official, since, according to the CEC resolution of October 20, 2020, № 404, the Commission receives the data from the bodies of the State Register of Voters, which, in turn, receive this data from territorial election commissions by any means, in particular, by phone or e-mail.
