Nazanin Zaghari-Ratcliffe

Nazanin Zaghari-Ratcliffe is a British-Iranian dual citizen, detained in Iran since 3 April 2016. In early September 2016 she was sentenced to five years' imprisonment for "plotting to topple the Iranian government"; the prosecutor general of Tehran had stated in October 2017 that she was being held for running "a BBC Persian online journalism course, aimed at recruiting and training people to spread propaganda against Iran". Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation, the Canadian news agency Thomson Reuters' charitable arm, travelled to Iran on 17 March 2016 to visit her family for Nowruz with her 22-month-old daughter. On 3 April 2016, members of Iran's Revolutionary Guard arrested her at the Imam Khomeini Airport as she and her daughter were about to board a flight back to the UK, her daughter's British passport was confiscated during the arrest, but returned, she remained in Iran under the care of her maternal grandparents so she could visit her mother. The exact reason for her arrest was unclear, though according to Amnesty International it is believed to be related to the 2014 imprisonment of several Iranian technology news website employees.

The head of Kerman province's justice department, Ali Tavakoli, said they had participated in projects run by the BBC and received funds from London: "This gang was running a number of projects and plans for anti-revolutionary Iranians based abroad for the BBC Persian, under the guise of legitimate activities. Financial aid for this group was provided from London under the pretext of charitable donations; the director of the team was an individual who has served the BBC as a mentor and teacher in a number of countries such as Malaysia and Afghanistan and his travels to these countries were paid for by British intelligence services." Zaghari-Ratcliffe has worked for the BBC World Service Trust, an international charity that provided training courses to Iranian citizen journalists and bloggers in its Iran Media Development Project's ZigZag magazine and associated radio programme. In 2014, several graduates were convicted and sentenced by Iran to up to 11 years in jail for their participation in these courses.

Nazanin worked for the BBC World Service Trust between February 2009 and October 2010, "in a junior capacity as a Training Assistant" according to the CEO of the Thomson Reuters Foundation, before moving to the Thomson Reuters Foundation. BBC Media Action described her role as "junior and purely administrative". According to Yadollah Movahed, the head of the Justice Department in the Iranian city of Kerman, as reported by the Iranian news network Press TV, Nazanin was arrested "over her involvement in post-election riots that engulfed Tehran and some other cities in 2009". Movahed said Zaghari was among the suspects who "conducted activities against the security of the country by designing websites and carrying out campaigns in the media” during 2009. According to Movahed, Nazanin was not arrested for activity inside Iran or for activity during her 2016 holiday to Iran: “Some members of the group were outside Iran, including the suspect Nazanin Zaghari”. Mashregh News, an outlet close to Iranian authorities, pointed to her alleged involvement with the human rights organizations Women Living Under Muslim Laws and Hivos as a motive for her arrest.

According to Press TV in June 2016, "The CGRI headquarters in Kerman province announced that Nazanin Zaghari had been identified after a large intelligence operation. She was one of the liaison officers of networks hostile to Iran abroad. According to this source, she was responsible for several missions, conducted her criminal activities under the direction of media and intelligence services of foreign governments."In early September 2016, she was sentenced to five years in prison "for plotting to topple the Iranian regime." The prosecutor general of Tehran stated in October 2017 that she was imprisoned for running "...a BBC Persian online journalism course, aimed at recruiting and training people to spread propaganda against Iran". PressTV in 2017 reported she had been "found guilty of spying and spreading propaganda against the Islamic Republic", describing the activities involved as her BBC World Service Trust work: She identified potential Iranian recruits and invited them to attend the training courses and reviewed their resumes, managed financial affairs related to the courses in Malaysia and India, picked trainers, assessed the performance of the participants and managed the ZigZag Academy’s websites.

On 23 August 2018, Zaghari-Ratcliffe was released on temporary licence for three days, standard practice prior to lengthier releases. However, Zaghari-Ratcliffe suffered from panic attacks after returning to prison, regretted having been given the temporary release, her husband said the temporary licence was a "cruel game" subject to conditions including the monitoring of her movements. In March 2019, the British Foreign and Commonwealth Office granted Zaghari-Ratcliffe diplomatic protection, raising the status of her case from a consular matter to a dispute between the two governments. Iran argues the designation is contrary to international law, the Master Nationality Rule, with Iran’s ambassador in London stating "Governments may only exercise such protection for own nationals... Iran does not recognise dual nationality". On 11 October 2019, Zaghari-Ratcliffe's daughter returned to her father in the United Kingdom to start school. In December 2019, the prosecutor general of Iran denied conditional release for Nazanin Zaghari, requested by her lawyer.

In February 2018, Richard Ratcliffe said he believed his wife's release w
