She is set to return today but relatives had hoped her release would be extended for a further two weeks.
It was the first time the 40-year-old mother had seen her daughter since 2016, when she was jailed and sent to Evin prison in Tehran after being found guilty of spying.
Yesterday her husband Richard, 43, who remains in Britain, described how Mrs Zaghari-Ratcliffe spent her last day of freedom at her daughter’s nursery.
He said: “Gabriella wanted her to see the teacher and the nursery. It was quite emotional for her, she wanted to show her to her friends and say, ‘Look, this is my mummy, and she’s out of prison’.
“She said she was struck by how Gabriella now has her own opinions. She can make bread and so on. Of course two years ago she couldn’t do.”
