As Iranians brace themselves for the effect of the latest US sanctions, a new social media campaign has been launched asking officials to disclose their wealth and how their relatives might have benefitted from their support for the regime.

The hashtag #where_is_your_kid? began trending on Twitter last week following news reports that some politicians' children were apparently being promoted to top state jobs despite a lack of experience and enjoying luxury lifestyles with their inflated wages.

The campaign gathered steam after the circulation of photos of the extravagant wedding of Mohsen Muradian, the son of Iran’s ambassador to Denmark, to Iranian model and designer Anashid Hosseini, which has been pejoratively dubbed the “royal wedding” by his critics.

One Instagram user responded to the photos by saying: “this royal wedding raises the question about the foundations of the Islamic Republic and why we should start to bury the Nezam (religious establishment) by holding such parties."

The couple said they personally covered all the costs of the wedding.
