Iran will hold its presidential election on Friday to choose a successor to Ebrahim Raisi, who died in a helicopter crash last month.

Candidates have promised to revive the economy.

But voters see little prospect of relief from a cost of living crisis without an end to international sanctions.

Al Jazeera’s Zeina Khodr has spoken to some of them in the capital Tehran.

Mohammad Reza Farzanegan is a professor of Economics at Philipps University of Marburg.

He says that corruption is also responsible for the ecomonic crisis in Iran.
