Former ambassador to the United Nations Sadeq Kharazi told Tasnim news agency on Saturday political groups and parties are allowed to express their views about nuclear talks between Iran and the major powers, but they have to "move within the framework of the instructions of the Leader of the Islamic Revolution."
"The Leader has charted the course of negotiations… I advise political activists to be careful not to use national interests as a pretext to pursue their individual and partisan objectives."
