The daughter and husband of Nazanin Zaghari-Ratcliffe, a British-Iranian woman jailed in Iran took part at a news conference in London on Thursday October 11, during which Nazanin's daughter cut a "welcome home" cake with her dad.

Nazanin's daughter, Gabriella, reunited with her father Richard after some 1300 days and their pictures together, appeared in the British press on Friday. Richard said at the news conference that he has been experiencing "a rollercoaster of emotion" since his daughter's return.

Gabriella was less than two years old when her mother was detained on the charges of "soft regime change" in Iran in 2016, a charge Nazanin has consistently rejected since her arrest.

Iran keeps many dual nationals in jail on similar charges including espionage without showing any evidence and foreign governments and the family members of jailed dual nationals believe Tehran uses them as pawns for political gain in their negotiations with foreign countries.

Nazanin Zaghari had said in a letter early October that her daughter was going back to the UK to go to school as she is now five years old.

During recent months, several reports said Zaghari may be released if the UK releases £400 million of Iran's frozen assets. Iran's foreign minister Zarif has been put forward by British officials, but Former UK Foreign Secretary Jeremy Hunt has denied Zarif's claim.

In her letter Zaghari wrote from jail, she accused the Islamic Republic of Iran of "auctioning" her "for hefty political gains," adding that she has lost all hopes in freedom.
