Jalili announced his decision on Wednesday afternoon, and Zakani did so on Thursday morning.
In reaction to Jalili’s withdrawal, Raisi said, “Dr. Saeid Jalili’s commitment-driven and timely decision indicated his revolutionary commitment and devotion.”
“I appreciated his untiring efforts,” he added.
“Today, is the day for a major campaign to help Iran take a leap,” the message further read.
Earlier, the reformist candidate Mohsen Mehralizadeh had dropped in favour of Abdolnasser Hemmati, the former moderate governor of the Central Bank of Iran.
Now only Mohsen Rezaei, Abdolnasser Hemmati, Amir-Hossein Qazizadeh Hashemi, and Ebrahim Raisi have remained in the race.
