Presidential elections are held following a campaign that saw huge rallies held in support of both incumbent Mahmoud Ahmadinejad and main opposition leader Mir Hossein Moussavi, suggesting the race would be closely fought.

In his first public appearance since the elections, supreme leader Ayatollah Ali Khamenei endorses Ahmadinejad's win, insisting the margin of victory -- some 11 million votes -- was too large to have been manipulated.

He urged critics of the electoral process to seek redress through legal channels and warned that perpetrators of violent unrest would be punished.
