Several election-day disturbances in the German capital have prompted calls for an inquiry into the results.
Long lines formed outside several polling stations in Berlin on Sunday as voters battled for additional ballots for simultaneous federal, state and district elections, as well as a city-wide referendum.
Despite the election officially ending at 6 pm (1600GMT), voters who stood in line by then were allowed to cast their vote.
Some polling stations ran out of ballots during the day, while others received ballots for the wrong district. This has led to a large proportion of ballot papers being declared invalid at some polling stations.
Berlin state’s top election official announced his resignation on Wednesday.
European MP Martin Sonneborn said on Thursday that his satirical party The Party would challenge the vote.
Clarity is not expected before the publication of the certified vote count on October 14 as to whether voting irregularities affect the result.
