TEHRAN -- Voting in the parliamentary elections in the Tehran constituency is likely to go to a second round.

With 4,000 out of the 5,000 ballot boxes in Tehran counted, some of the candidates seem to have to compete in a runoff as there were no clear winners among them, officials say. “The law says any candidate who wins at least 20% of the valid votes can enter Parliament in the first round, but if they fail to garner at least 20% of the ballots, they will probably go to a second round,” said Governor of Tehran Province Alireza Fakhari.
