Life inside Iran's notorious Evin prison: It's about breaking you down... treating you like an animal
When Ana Diamond went on holiday to Iran to visit family never in her worst nightmares did she imagine it would end the way it did.
At the airport to fly home her passport was taken away. After a year unable to leave the country one day things got much worse.
Iranian officials had seen photos of Ana Diamond with politicians when she volunteered for the Conservatives.
They arrested her and her parents for spying and held in the notorious Evin prison spending seven months in solitary confinement. She says it was torture.
Ana is sharing her story to try and help other foreign nationals detained in Iran who maintain their innocence. One of those is Nazanin Zaghari-Ratcliffe who has been in the same jail Ana was held in for the past three years.
Her husband Richard met her to thanks her and talk about what more they could do to try and get Nazanin out.
Ana and Richard want to visit the UN with the families of other prisoners later this year knowing their voices are stronger together.
