British Foreign Secretary David Miliband said Sunday that Iran would release without charge one of two British Embassy employees still being held in Teheran after seven others were freed last week.
Iran had claimed that the eight had been released but Miliband's statement appeared to contradict that. The British foreign secretary told the BBC that the claims against the staff had "absolutely no substance."
A lawyer for a ninth man, political analyst Hossein Rassam, said he has been charged with harming Iran's national security.
Iranian officials detained the embassy staff just over a week ago, accusing them of fomenting unrest.
All are Iranian nationals, and seven of them were released on June 29.
