Former Iranian President Mohammad Khatami has called for a referendum on the legitimacy of the government.
‘The only way out of the current situation is to hold a referendum, people should be asked whether they are happy with the current situation,' said Mr Khatami.
Clashes erupted again last Friday in central Tehran between police and reformist protesters Friday after another former president, Akbar Hashemi Rafsanjani, declared the Islamic Republic in crisis after the disputed 12 June poll.
The election results gave hardline incumbent President Mahmoud Ahmadinejad a landslide victory and sparked the biggest demonstrations in Iran since the 1979 Islamic revolution.
At least 20 people died in the violence before riot police and Islamic militiamen suppressed the nightly protests.
Mr Khatami's call for a referendum indicates the reformist camp is still unwilling to give in quietly despite the security crackdown and the arrest of hundreds of people, including leading reformers, journalists, activists and lawyers.
The reformers are aware of the rising expectations of a youthful population, mostly born since the 1979 revolution, argue the Islamic Republic must become more open and accountable to the people if it is to survive.
