'I do apologise,' says Boris Johnson as he promises to meet husband of jailed Briton

Boris Johnson is to meet the husband of jailed British mother Nazanin Zaghari-Ratcliffe on Wednesday to discuss the possibility of her being offered "diplomatic protection" as part of Government efforts to secure her return from Iran.

Downing Street confirmed that the Foreign Office is looking into the possible use of the status after Richard Ratcliffe spoke with the Foreign Secretary by phone at the weekend.
