Nazanin Zaghari-Ratcliffe: Gove says he does not know why she was in Iran

Environment Secretary Michael Gove has told the BBC's Andrew Marr that he does not know what Nazanin Zaghari-Ratcliffe was doing in Iran.

The interview came after Boris Johnson, the foreign secretary, was criticised for claiming the dual British-Iranian citizen had been "training journalists".

He has since said the government has "no doubt" she was on holiday "and that was the sole purpose of her visit".
