In this video, which appeared on different reformist websites, Ahmadinejad is clearly telling his audience that he "felt a halo surrounding him" while he was making his speech in 2005.
The clip was broadcast after the president denied it in a TV programme on Saturday. Meanwhile, his main rival Mirhossein Mousavi accused the president of being 'superstitious' and of 'lying insolently' to the country.
Extracts from the video: "A member of the delegation told me: 'I saw a light surrounding you'", Ahmadinejad told his audience. He continued: "I felt it too...I felt the atmosphere changing. None of the leaders present blinked in 27, 28 minutes. I am not exaggerating (...) Everyone was astonished (...) They all opened their eyes and ears to listen to the Islamic republic message."
