An observer from the Organization for Security and Cooperation in Europe (OSCE), Neil Simon, said there were problems at polling stations in Ukraine during the parliamentary election on Sunday.

“As of now I do not want to speak about something positive or negative so that another observer would reject this information later. However, there were not many polling stations [in Ukraine] that did not have problems at all,” Simon said in an interview with Voice of Russia radio station, but did not specify the nature of the problems.

The OSCE observer said that the detailed report from Sunday’s election process will be ready and revealed on late Monday afternoon after all OSCE observers in Ukraine sum up their results from all polling stations across the country.

Meanwhile, the Ukrainian Interior Ministry said in a statement that police received from citizens a total of 237 calls on Sunday that were about alleged violations at the election.

According to the statement, most of the calls were regarding the illegal campaigning at polling stations, acts of bribing voters, violations of election procedures, acts of hooliganism and others.
