CHARITY worker Nazanin Zaghari-Ratcliffe jailed in Iran has threatened to go on hunger strike, her husband revealed.

She made the harrowing threat last week as she was transported back to Evin prison in Tehran after a few days' home leave.

Her husband Richard told Sky News Nazanin, 40, was "desolate, so broken".

He said the family had to talk her out of starving herself.

Nazanin was arrested in April 2016 for allegedly scheming to overthrow the Iranian regime, which she has always denied.

Richard also praised Jeremy Hunt, the new Foreign Secretary who took over from Boris Johnson, describing him as a "big brother" to their cause.

He said: "I wanted him to make her a priority - it feels like he has.

"He's issued statements saying he thought she was innocent. He's been as strong as we could have wanted.

"It feels like she's got a big brother in the playground."

Last week we revealed how Nazanin wished her temporary release from an Iranian jail had never happened.

In an open letter to Iran's foreign minister Mohammad Javad Zarif, Richard says his wife has "numbness in her legs" after suffering two panic attacks on her return to prison.

He has now described his wife's hasty return to jail as “a cruel game” revealing even the prison guards "cried".

He writes: "She wished she had never been released. She said she felt like one of the radical Islamists' captives - as though she had been paraded on the balcony then hidden back away."

He said the family feels "held together by sellotape".

Despite promises from prosecutors that her furlough from jail would be extended, hours later she was back behind bars.

Earlier she was clearly overjoyed to be out of custody, Richard revealed in an interview with Radio 4 this morning.

Richard, who has been unable to get an Iranian visa, said his wife's temporary release initially appeared to be a "very good sign", but said it felt "pretty cruel at the end of it".

Touching images taken earlier this week showed her cradling Gabriella in her arms in Damavand at the start of her release from prison.
