Nazanin Zaghari-Ratcliffe has been denied an extension of her temporary release in Iran and has returned to prison.
Her husband Richard Ratcliffe announced that an application to extend her surprise three day furlough had been denied.
The charity worker is two years into a five year prison sentence after being charged with national security offences, which she denies.
Iran’s Revolutionary Guards seized Mrs Zaghari-Ratcliffe at the end of a two-week holiday with her daughter Gabriella to visit her parents.
Gabriella was taken to live with her grandparents.
Her lawyer submitted a request for the extension on Saturday and had been hopeful that it would be extended.
Mr Ratcliffe said: “Her lawyer is confident that he will get it extended. It’s standard that you get three days in the beginning, but in most cases it’s extended.
“If you’ve got out the door of the prison, you usually get longer than three days.”
The three-day long furlough is the first time she was allowed out of prison and coincided with the Muslim celebration of Eid.
Mr Ratcliffe’s long-standing request for a visa to Iran has not yet been granted. It means he has also not seen his daughter in more than two years.
