Iranians have voted in a presidential run-off election between a reformist and a conservative hardliner, with the result expected on Saturday.

The run-off took place on Friday, one week after the first round of voting ended without a clear winner. The election was called after President Ebrahim Raisi died in a helicopter crash in May.

Reformist Masoud Pezeshkian is a former deputy parliamentary speaker and health minister.

Saeed Jalili is a hardliner and a former secretary of the Supreme National Security Council, a body in charge of defense and foreign affairs.

The focus is on how voters evaluate Iran's current hardline foreign policy.

Pezeshkian says he wants to improve relations with the United States and Europe, so that they would lift sanctions on Iran.

Jalili argues that even if Iran remains in conflict with the West, it can overcome sanctions through measures such as developing domestic industries.

Pezeshkian and Jalili cast their votes as their supporters looked on.

A 62-year old woman who voted for Pezeshkian said he has a gentle nature and should be able to build good relations with countries around the world.

A 30-year old woman said she voted for Jalili because she could not tolerate the humiliating diplomacy of the West.

Iran's hardline conservatives have a solid support base, but it is believed that higher voter turnout could be advantageous to the reformist camp.
