Nazanin Zaghari-Ratcliffe, the detained British-Iranian aid worker sentenced to five years in jail in Iran, is reportedly to face a second trial on new security charges. Iran’s Tasnim news agency quoted the head of Tehran’s revolutionary court, Musa Ghazanfarabadi, as saying she would be ordered “to present an attorney and then the court will convene”.

Ghazanfarabadi said the new charge against Zaghari-Ratcliffe was security related, but did not specify what it was, Tasnim reported.

Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation, was arrested in 2016 as she was heading back to Britain with her daughter after a family visit. She was convicted of plotting to overthrow Iran’s clerical establishment, a charge denied by her family and the foundation. In a statement last week, the foundation said it totally rejected “the renewed accusations that Nazanin is guilty of spreading propaganda”.

Her husband, Richard Ratcliffe, told the BBC that she had met a judge “who said there would be a charge of spreading propaganda against the regime. That’s a very mild form of security charge, so hopefully it’s just that.”
