The daughter of detained Briton Nazanin Zaghari-Ratcliffe has returned to the UK after more than three years with her family in Iran.
Gabriella, five, remained in Iran after her mother was arrested in April 2016 in Tehran at the end of a family visit and was allowed to make weekly visits to prison.
The youngster returned to the UK shortly before midnight on Thursday.
Just hours after being reunited with her father Richard Ratcliffe, the pair held a press conference in the UK's Houses of Parliament on Friday.
Mr Ratcliffe has not seen her since her mother was imprisoned as he has been denied a visa to visit Iran. Gabriella had stayed with his wife’s parents.
The girl has little English after more than three-and-a-half years in Iran and her parents have decided to continue her education in the UK.
It was a hard goodbye for Nazanin and all her family,” said Mr Ratcliffe had said earlier. “But let us hope this homecoming unlocks another.”
Mrs Zaghari-Ratcliffe, a charity administrator and British-Iranian dual national, is seeking release on health grounds from prison after being jailed for five years on unspecified espionage charges.
Her supporters say she is being used as a pawn in the diplomatic battle between the UK and Iran. They have fought a vocal campaign for her release.
The family’s MP, Tulip Siddiq, said: “It is heart-warming to see Gabriella reunited with her father after 1,300 days in Iran, but heart-breaking that she is separated from her mother Nazanin.”
