Mohammad Marandi, an advisor to the Iranian nuclear negotiating team was removed from his post as the international affairs deputy of the University of Tehran.

The political commentator, whose statements about the nuclear negotiations have received a lot of mixed reactions over time, was sacked upon reported differences with the dean.

Shargh daily Sunday quoted Marandi as saying that the reason for his dismissal was his objection to "the sale of degrees and Tehran University's loss of reputation".

Marandi was the dean of Tehran University's World Studies Center. However, academics in Tehran say the center no longer exists. That could explain Marandi's official title as "Former head of the university's World Studies Center."

Marandi was ridiculed by some Iranian commentators in recent months for having said last summer that "a hard winter in Europe" will force European powers to come back to the negotiating table. Marandi had predicted: "The winter is coming, and the EU will have to face a paralyzing energy crisis."

A few months later pundits in Iran scorched Marandi over his prediction while Iran itself faced energy shortage in winter.

Heshmatollah Falahatpisheh, an outspoken critic of the government in foreign policy, said predictions by Iranian officials that Europe would plunge into cold, and they would run back to nuclear negotiations with Iran have turned out to be "illusions."

Marandi was born in the US in 1966. He is the son of Alireza Marandi who is Supreme Leader Ali Khamenei's family doctor. When he first came to Iran after his father was appointed Health Minister, Mohammad was only 13.
