Nazanin Zaghari-Ratcliffe, a 38 year old mother and charity worker from London, was detained in Iran while on a family holiday and separated from her 2 year old daughter, Gabriella. She was sentenced to five years in jail. Her family still don't know why she's being held. 

As mothers from across the UK we've started this open letter to help reunite Nazanin with her young daughter Gabriella - an unimaginable situation which no mother should ever have to bear.  Please add your voice today and help bring Nazanin home. 

This open letter will be delivered to the Iranian embassy and published in the press.
