As reported by Censor.NET, Soboliev, Samopomich MP, wrote this on his Facebook page.
The demonstration is planned to start at 3:30 p.m. near the Central Election Committee building in Kyiv. The demands are to cancel the decision of the Kryvyi Rih election committee, which announced Vilkul mayor despite violations of the voting process, and to replace those members of the committee who voted in favor of the decision.
According to Soboliev, the re-elected mayor Vilkul and head of the CEC Okhendovskyi have been friends for a long time.
People's Front MP Leonid Yemets has also promised to join the protest.
"Although People's Front has not participated in the election, this does not mean we don't give a damn. So I will be there at 3:30 p.m., protecting the choice of Kryvyi Rih," Yemets wrote on his Facebook page.
