More than 100 MPs appear to have snubbed an invitation to celebrate Iranian President Mahmoud Ahmadinejad's election win, local press reports say, reported BBC.
All 290 MPs were invited to the victory party on Wednesday night but 105 did not turn up, the reports say.
A BBC correspondent says the snub is a sign of the deep split at the top of Iran after disputed presidential polls.
Meanwhile, 70 academics were arrested after meeting key protest leader Mir Hossein Mousavi, his website says.
The report on the Kalemeh website said it was not clear where the university professors were taken.
Hundreds of opposition protesters and activists are believed to have been taken into custody and at least 17 people have died in the unrest that followed the 12 June election.
Severe reporting restrictions in Iran mean the BBC cannot verify the reports.
Supreme leader Ayatollah Ali Khamenei said again on Wednesday he would "not yield" over the election result.
