Nazanin Zaghari-Ratcliffe’s husband, Richard Ratcliffe, is due to have talks with the new Foreign Secretary, Liz Truss, on Sunday.
Ms Zaghari-Ratcliffe has been held hostage in Iran since 2016 but the last four foreign secretaries have not been able to get her back to the UK.

Richard Ratcliffe told the BBC’s Andrew Marr that his wife spoke to their daughter Gabriella most days, while under house arrest.
