Nazanin Zaghari-Ratcliffe is set to return home to the UK after being released from prison in Iran.
The British-Iranian mother has been detained in Iran for nearly six years after being arrested while taking her daughter Gabriella to see her parents in 2016. Both Ms Zaghari-Ratcliffe and fellow detainee Anousheh Ashoori are believed to be heading to Tehran airport today to leave the country.
Tulip Siddiq, Ms Zaghari-Ratcliffe's MP in Hampstead and Kilburn, wrote on Twitter: "Nazanin is at the airport in Tehran and on her way home." The Foreign Office has not commented on the reports and earlier Boris Johnson said negotiations about Ms Zaghari-Ratcliffe were "moving forward" but "going right up to the wire".
