Almost 36 hours after the apparent resignation of Iran’s foreign minister, there are finally some answers to the many questions it raised. For instance, his superior, president Hassan Rouhani, has not accepted his resignation, which is required under Iranian law. Neither has the top decision-maker in the country, Ayatollah Ali Khamenei – if one is to believe cryptic rumours of a “high-ranking official” having told the diplomat that his exit is not “expedient”. Mohammad Javad Zarif is back at work, joining Rouhani in greeting a visiting Armenian delegation early on Wednesday.

But there is still the question of why Zarif suddenly decided to go on Instagram at midnight on Monday, expressing gratitude to “the dear and honourable Iranian people for the last 67 months” and apologising for his “incapacity” to continue serving in his post. Being under fire from all sides is certainly not a novelty for the ever-smiling Iranian chief diplomat. For years, he has been adored and despised for essentially the same thing: his ability to convincingly make Iran’s case to the world in fluent English, with a strong grasp of how western media works.
