In the early years of the revolution, Mousavi was the editor-in-chief of Jomhouri-e Eslami, the official newspaper of the Islamic Republican Party, before being elevated to Minister of Foreign Affairs and eventually the post of Prime Minister. He was the last Prime Minister in Iran prior to the 1989 constitutional changes which removed the post of the prime minister; he then went into semi-retirement for the next 20 years. He remains a member of the Expediency Discernment Council and the High Council of Cultural Revolution. However, he has not participated in their meetings for years, which is interpreted by political analysts and commentators as a sign of his disapproval.
