However, this was a small if dramatic example of the uncertainty that followed the collapse of Ben Ali's Presidency on Friday. The bigger political questions take over from the deposed autocrat's fate.
After more confusion in Tunis --- had the military staged a coup? was the Speaker of Parliament Fuad Mbazza assuming authority? --- former Prime Minister Mohammed Ghannouchi announced on television, "Since the president is temporarily unable to exercise his duties, it has been decided that the prime minister will exercise temporarily the [presidential] duties."
Some politicians, lawyers, and activists protested that Ghannouchi's move was unconstitutional, since the Presidency should have gone to Mbazza. Academic Noureddine Miladi declared:
It is manipulation of the constitution. It has been argued by the likes of Iyad bin Ashur, one of the top lawyers in Tunisia. He argues that the head of parliament is the only legitimate party able to form a legitimate [caretaker] government, for about 45 days and then [they must] call for elections.
He [the speaker of the parliament] is supposed to oversee the success of the election. Ghannouchi is part of the same corrupt political elite as Ben Ali. There is nothing new in what happened today, it is a different twist of the game.
The response to these charges, it was claimed (but not confirmed), was that Mbazza was ill and that Ghannouchi would hand over the Presidency "in a few days".
Ghannouchi, a trained economist, has been close to Ben Ali for many years. He was Prime Minister since 1999, serving previously as Minister for International Cooperation and Minister of Foreign Investment..
Ghannouchi said his actions were in line with Article 56 of the constitution, though observers pointed out that the line of succession should legally pass first to the speaker of parliament. Noureddine Miladi, a sociology and media lecturer of Tunisian origin, explained.

And there was still tension on the streets, with reports of looting of government buildings and houses in Tunis and other cities. Reports continued of protests outside the Ministry of Interior calling for Ghannouchi's immediate resignation. The State of Emergency Law, invoked yesterday, is still in effect. There is an overnight curfew, and police have the authority to use any necessary force to halt a suspect who does not heed a warning to halt.
