The victories of principlists come despite efforts earlier by reformists through multiple meetings with independent councilors to secure the chair of the council.
Ayatollah Akbar Hashemi Rafsanjani has said that those involved in partisan activities should not overlook ethics in political rivalries.
Proponents and opponents of former President Ahmadinejad seem to see eye to eye on one matter: his trial in a court of law.
An official at the Presidential Office has said that the youth should not allow to be affected by extremist groups and those who think that the revival of moderation would sound their death knell.
