UK Foreign Secretary Boris Johnson and his Iranian counterpart have spoken “frankly” about jailed Briton Nazanin Zaghari-Ratcliffe.
He and Mohammed Javad Zarif discussed issues including her case and that of other dual nationals held in Iran.
Ms Zaghari-Ratcliffe has been held in Tehran since April 2016, after being accused of spying, a charge she denies.
Her husband, Richard Ratcliffe, spoke of his “hopes and fears”, telling the BBC “it could go any which way”.
In what was described as “a useful meeting”, Mr Johnson and the Iranian foreign minister talked for two hours in Tehran on a range of subjects including the nuclear deal, as well “obstacles in their relationship”.
