Violations registered by observers from the election headquarters of presidential candidate Petro Poroshenko do not affect the voting at the presidential elections in Ukraine, the candidate’s headquarters reported.

"So far, these violations do not affect the voting. And they do not distort its results," member of Poroshenko's election headquarters MP Serhiy Alekseyev said at a briefing in Kyiv on Sunday.

According to him, observers report such violations as campaigning near the premises of a polling station in Kamianske, Dnipropetrovsk region, buses "with people from Kyiv" going to Vasylkiv district of Kyiv region, which were blocked by the police.

Observers from one of the candidates have branded badges, which can be viewed as hidden campaigning, Alekseyev said.

Meanwhile, another member of Poroshenko's election headquarters MP Maksym Savrasov said that 30,000 observers and 30,000 members of election commissions from Poroshenko's team are working at polling stations on Sunday.

"There are observers and members of the commissions from the Petro Poroshenko Block at all polling stations in the country," Savrasov added.
