The former president's visit has removed rumors of restrictions on his agenda, but his hasty departure has raised many questions.

Many question marks arise around the arrival and departure of former Iranian President Ahmadinejad during his visit to the 2020 Expo exhibition in Dubi. First, his very departure from Iran constitutes confirmation that the authorities have given the former president official permission to come and go without restrictions even taking into account the criticism he tends to level at the government.

His arrival in the gulf led to a series of speculations in the Arab world about the purpose of the visit, but his sudden and rapid departure from the place raised even more speculations.

The Fares news agency claimed that he was recommended to leave by officials, but there were other reports that he was deported by the police.

He was accused of planning to take part in "political and populist activities" that would undermine security at the Expo conference, Jahan News reported Monday.

The Iranian consulate in Dubai also prevented him from holding a press conference there, sources said in Iran.

At the moment there is no clear confirmation of the chain of events.
