ANKARA (Reuters) - A mild-mannered cleric known for decades as an establishment insider, Iran's President Hassan Rouhani reinvented himself as a rabble-rousing political street fighter to secure a decisive re-election victory against a united conservative bloc.

Now, having stoked his supporters' yearning for change, he faces the harder task of satisfying them without bringing a backlash from the conservatives who still control most of the levers of power.
