The Iranian presidential hopeful Mir-Hossein Mousavi has vowed to follow the reformist path of former President Mohammad Khatami, the satellite Press TV reported on Wednesday, Xinhua reported.
"I, like you, believe that the correct path lies in reforms that include a return to principles and a rebirth," Mousavi told Khatami in a letter cited by Press TV.
In a statement released on Tuesday, Khatami, who had already announced his bid for presidency, formally withdrew from the campaign in favor of former Iranian Prime Minister Mir-Hossein Mousavi, another reformist, who announced his run for presidency last week.
Mir-Hossein Mousavi, an politician, painter and architect, was the prime minister of Iran from 1981 to 1989 under the then President Ayatollah Ali Khamenei (now Supreme Leader). He was the last prime minister of Iran before the change in the constitution which removed the post.
Mousavi has repeatedly criticized the incumbent government's economic policy which he called an alms-based one.
The country's upcoming presidential election will be held in June.
