Alireza Zakani, the current Mayor of Tehran and a hardliner politician, has formally registered to run in Iran's presidential election scheduled for June 28.

Known for his conservative stance and nicknamed the "revolutionary tank," Zakani is returning to the presidential fray after withdrawing in 2021 to support Ebrahim Raisi, who died in a helicopter crash on May 19.

Zakani's political career has been marred by controversy for his aggressive tactics, particularly against reformists. Despite his bold rhetoric, he has faced significant criticism, even from state media, which questions his suitability for higher office.

His tenure as mayor has not been without its problems, including disputes over urban policies like mosque constructions in parks and the enforcement of the hijab on public transport, which have sparked internal conflicts within the conservative camp and the city council. 

Financial and familial scandals have also dogged Zakani. His administration's decision to provide financial deposits to municipal managers for housing needs led to a backlash from several city council members. More personal allegations have surfaced, including nepotism involving his son-in-law and questionable financial dealings by his daughter and her husband with the Islamic Development Organization.

Zakani’s political past includes a stint as the chair of the JCPOA - nuclear deal - commission in the parliament in 2010s, where he transitioned from presenting an impartial stance to becoming a vocal opponent of the agreement.
