The husband of a London woman jailed in Iran was today travelling to the United Nations in New York to press for her freedom.
Richard Ratcliffe’s annual pilgrimage to the UN General Assembly came as Theresa May was making a personal appeal for Nazanin Zachary-Ratcliffe to be released.
Mrs May and the Iranian president Hassan Rouhani are due to meet for talks in New York later today.
A senior Government official said: "The PM will express serious concern at Nazanin's on-going detention and call for her to be released upon humanitarian grounds."
Mrs Zaghari-Ratcliffe, a charity worker, is half way through a five-year prison sentence for allegedly plotting to overthrow the Iranian government. She emphatically denies the allegations.
Mr Ratcliffe has been refused a visa to see her in Tehran and the couple’s four-year-old daughter Gabriella has not been allowed to return to London.
Gabriella is living with her Iranian grandparents.
Mr Ratcliffe has traveled from the family home in Hampstead, north London, to try to lobby Iranian delegates at the UN and to meet other families of Iranian detainees.
