Karroubi made the remarks during a meeting with the family of Mir-Hossein Mousavi, the Green Movement leader who has been under house arrest since 2011. Both men were presidential candidates in the disputed 2009 election, which they contended was marred by fraud and irregularities.
“In the 2009 election, Mr. Khamenei not only did not tolerate the people’s vote, but he supported fraud and violent suppression and accused us of sedition, lack of insight and indecency,” Karroubi said.
The 2009 election, in which authorities swiftly declared Mahmoud Ahmadinejad the winner, triggered one of the biggest street unrests since the 1979 revolution, with mass demonstrations and a crackdown by security forces. Khamenei at the time urged Iranians to accept the result and later warned protesters to end rallies.
"Khamenei claimed insight, but destroyed the economy, culture, security and ethics, and what you see today is the product of that wrong approach,” Karroubi was quoted as saying by Iranian media.
