A representative of Iran's supreme leader said Barack Obama taking office, as U.S. president did not mean Tehran's ties with Washington would change, a news agency reported on Wednesday. Supreme Leader Ayatollah Ali Khamenei, who has ultimate authority over policy in the Islamic Republic, has yet to comment on Obama's presidency or his offer to extend a hand of peace if Iran "unclenched its fist". The leader has representatives to many institutions and regions. Though not a perfect guide, their comments can give an indication of views prevalent among Iran's leadership.
