The competition in Tehran was between reformist candidates campaigning under the slogan of “Hope”, who had aligned themselves with Rouhani, and Principlists who make up the majority in the Islamic City Council of Tehran.
Mohsen Hashemi, the son of the late Chairman of the Expediency Council Ayatollah Akbar Hashemi Rafsanjani, was the main figure of the Hope list.
The principlist list was led by Mehdi Chamran, the current chairman of the Council.
