Meanwhile, the Obama Administration called on Tehran to allow the rally. "By announcing that they will not allow opposition protests, the Iranian government has declared illegal for Iranians what it claimed was noble for Egyptians," National Security Advisor Tom Donilon said in a statement.

0705 GMT: And so there were speeches, including one by President Ahmadinejad, and a ceremony for the 32nd anniversary of the Islamic Revolution.
There may be no better illustration of how the day came and went than this declaration from Kayhan. According to the newspaper, 50 million --- two-thirds of the Iranian population --- came out for the regime
Debates over the size of the crowd for the day continue. But far more significant may be whether the day had any significance beyond a setpiece to make the ritual statement of Iranian progress and to denounce the "arrogance of power" of the "West".
The Iranian publicity machine featured Mahmoud Ahmadinejad's hour in Azadi Square in Tehran, but the speech had little of signficance beyond a brief passage setting out the President's challenge to his rivals within the establishment over his economic programme. Ahmadinejad set up the subsidy cuts and his expansion of power as moves for "justice", but he prefaced this with the unreal claim that he would eliminate unemployment by the end of his term in 2013.
Press TV, with its international audience, soon left behind the events to focus on Egypt. And while State TV continued to loop images of the ceremonies in Tehran and elsewhere, this morning the anniversary of the 1979 Revolution has been relegated, even by the Islamic Republic News Agency, to a place well behind the departure of Hosni Mubarak. (Indeed --- and make of this what you will --- IRNA's report on Ahmadinejad and the 22 Bahman ceremony cannot be loaded.)
Meanwhile, the regime was also attempting to break up any prospect of an opposition show on Monday. There were more arrests of journalists and activists on Saturday and disruption and jamming of communications.
It is impossible to tell whether the Green Wave will make any appearance in 48 hours. But perhaps the symbolic measure of the continuing struggle for legitimacy came last night.
A report came through that, if someone in wanted to learn of the full extent of the regime's celebration of 22 Bahman by typing "Bahman" into a Google search, he/she would be out of luck. The word is now blocked.
