Tasnim � Tehran is going to host a congress on Tuesday in commemoration of former Iranian president and chairman of the country�s Expediency Council Ayatollah Akbar Hashemi Rafsanjani on his first death anniversary.

Iranian President Hassan Rouhani is going to deliver a speech at the congress, a son of the late cleric, Mohsen Hashemi, told Tasnim on Sunday.

He noted that First Vice-President Eshaq Jahangiri and Hassan Khomeini, grandson of late founder of the Islamic Republic Imam Khomeini, will also address the commemorative gathering.

Ayatollah Rafsanjani was laid to rest at the mausoleum of Imam Khomeini south of Tehran in January 2017.
