British Iranian national Nazanin Zaghari-Ratcliffe has had her British passport returned, according to MP Tulip Siddiq.

The Hampstead and Kilburn MP tweeted: “I am very pleased to say that Nazanin Zaghari-Ratcliffe has been given her British passport back.

“She is still at her family home in Tehran. I also understand that there is a British negotiating team in Tehran right now.

“I will keep posting updates as I get them.”

When asked about her possible release, her lawyer, Hojjat Kermani, told Reuters: “I am hopeful that we will have good news soon.”

Zaghari-Ratcliffe has been detained in Iran since her arrest in 2016 on charges of plotting to overthrow the government – allegations she has always denied.

A £400 million debt relating to a cancelled order for 1,500 Chieftain tanks dating back to the 1970s had been linked to the continued detention of Mrs Zaghari-Ratcliffe and other UK-Iranian dual nationals held in the country.
