LONDON (Reuters) - The West should not push Iran too far in talks over the Islamic republic's nuclear ambitions because failing to get a deal could bolster hardliners in Tehran, a former British foreign minister warned on Friday.
But Jack Straw told the BBC he was "optimistic", on returning to London from Iran where he led a British delegation including former Chancellor Norman Lamont, Conservative member of parliament Ben Wallace and Labour lawmaker Jeremy Corbyn.
