Nazanin Zaghari-Ratcliffe has been sentenced to one more year in prison in Iran, a development that prompted an instant backlash from the United Kingdom’s Prime Minister Boris Johnson.

A revolutionary court in Iran has sentenced a 43-year-old British Iranian woman to one year in prison on Monday after she was convicted of propaganda against the Iranian government, her lawyer said.

She has already spent four years in a prison in the Iranian capital, Tehran, and is serving a five-year sentence before being released into house arrest during the coronavirus epidemic in March 2020.

Her lawyer, Hojjat Kermani, told the Emtedad News website: “Nazanin Zaghari was sentenced to one year in prison and one year in exile for propaganda against the Islamic Republic.

Karmani said he would apply for the new sentence within 21 days under Iranian law.

The new allegations relate to Zaghari-Ratcliffe’s alleged involvement in a 2009 protest in front of the Iranian embassy in London.

Zaghari-Ratcliffe’s family and his colleagues at the Thomson Reuters Foundation (TRF) charity have denied the allegations against her.

Zaghari-Ratcliffe, a project director with the TRF, was arrested at Tehran airport in April 2011 and later convicted of plotting to overthrow the country’s religious establishment – a charge that she, her supporters, and rights groups deny.

His previous sentence has recently raised hopes of a return to the UK.

But after she was released from house arrest last month, she was ordered to return to court immediately to face new publicity charges.

Johnson of the United Kingdom, whose government pressured Tehran to release Zaghari-Ratcliffe and allow her to return, criticized the revolutionary court’s decision.

“I don’t think it’s fair that Nazanin should be jailed anymore,” Johnson told reporters.

He added that Britain was working with the United States on the issue of dual citizenship in Iran’s prisons.
