Tehran, Iran (CNN) -- Iran's Supreme Council of Cultural Revolution on Tuesday evening booted former opposition presidential candidate Mir Hossein Mousavi from his post as head of the Academy of Arts, Iranian media reported.
The council proposed poet Ali Moalem Damghani to replace Mousavi.
Mousavi challenged Mahmoud Ahmadinejad for the presidency, and, along with another candidate, questioned the legitimacy of the June 12 vote count, which Iranian officials declared for Ahmadinejad.
The questions prompted weeks of sometimes violent and deadly protests.
Neither the semi-official Fars news agency nor the official Islamic Republic News Agency (IRNA) offered a reason for Mousavi's firing. Mousavi had been president of the academy since 1999, IRNA said.
Fars said Ahmadinejad will make the formal appointment of the head of the academy.
