The parliament that takes office after Friday's elections will have a major impact on the direction of Iran's Islamic revolution and on who will succeed the Ayatollah Ruhollah Khomeini.

At stake are 82 seats in the 270-member Majlis, Iran's parliament. An estimated 22 million people were eligible to cast ballots. Polls were scheduled to be open from 7 a.m. until 5 p.m. (9:30 p.m. EDT).The election is the third parliamentary contest since Khomeini's Islamic revolution toppled the late Shah Mohammed Reza Pahlavi in 1979.

Friday's balloting is the second round of a two-part election process. The other 188 seats in the Majlis were decided on April 8. Interior Minister Ali Akbar Mohtashemi said a record 17 million people voted in the first round.
