Questions grow as Ahmadinejad stays out of sight
Speculation over whereabouts of Iranian president, who has not been seen since Monday

‘Speculation is intensifying about the whereabouts of Mahmoud Ahmadinejad, who claimed victory in the Iranian presidential election but has not been seen in public since Monday, when he was in Russia for a conference.

Iranian media have reported only that the president was greeted by a number of senior government officials when he arrived home late on Tuesday.

Ahmadinejad’s last public appearance in Iran was on Sunday, when he gave a combative press conference at his Tehran office for foreign and local media, and compared the supporters of the defeated election candidate Mir Hossein Mousavi to football fans whose team had lost.

He then addressed a crowd of tens of thousands of supporters at Vali Asr square in the centre of the capital.

Analysts and diplomats say that the fact that Ahmadinejad has not been seen for three days as street protests and political turmoil rage suggests his position may have been weakened. Rallies backing him have been far less well attended than those organised by the Mousavi camp.’
