A former Brockley resident is still being held in an Iranian prison without charge and is separated from her young daughter on her birthday.

Nazanin Zaghari-Ratcliffe, a British-Iranian national - has been in prison since April 3, when she was separated from her daughter Gabriella.

Nazanin's husband, Richard Ratcliffe, will celebrate his daughter's birthday near the Iranian embassy in Hyde Park.

Mrs Zaghari-Ratcliffe, who is a project worker for Thompson Reuters foundation, lived in Tywhitt Road, Brockley for three years.

She stayed with Clare Cowen, of the Brockley Society, who said: "I have known Nazanin for 10 years, her mother stayed with us during a visit.

"We were at her wedding in 2009 and I attended her ceremony for British Citizenship."

Gabriella had her British passport confiscated by Iranian authorities and her mother is being detained 621 miles from her in Kerman prison.

Mr Ratcliffe is currently without a visa to go to Iran, having been strongly advised not to travel at present, and he last saw Gabriella on March 17.

The toddler is being looked after by her grandparents, and under Iranian law only her father or mother can bring her home.

The Free Nazanin Campaign event will also be the culmination of its birthday card campaign, where thousands of people across the globe have been sending cards via Iranian embassies in London and around the world.

The event will be celebrated by family and friends, neighbours, Gabriella's MP Tulip Siddiq, representatives of Change.org, and others.

People are invited to send cards or support the online petition at Change.org with 750,000 signatures to free Nazanin and reunite the family.

Mr Ratcliffe will attempt to present a card to the embassy at 1pm and ask that they pass it on to his daughter.

He said: "I kind of want to try and make it reasonably celebratory as well, so it's not too sad.

"I am overwhelmed by the public outcry about my baby daughter's birthday.

"I am grateful that she is with her loving Iranian grandparents but, nonetheless, I want her and her mother together and back home with me as soon as possible.

"It has been really moving for all my family here to see the kindness of people across the country connecting with our story, making cards for Gabriella with their own children or grandchildren, and doing something to make Gabriella's world a better place.

"In my bones, I feel it is that kindness that will in the end bring them home."
