Iran's hardline former president Mahmoud Ahmadinejad called for the immediate holding of free presidential and parliamentary elections in a letter to supreme leader Ayatollah Ali Khamenei published on Thursday.
The call from a man, whose name is synonymous with the bloody repression of mass protests against his controversial re-election in 2009, marked a new act of defiance against a political establishment that has long since turned against him.
Ahmadinejad made no specific reference in his letter to a wave of unrest that swept Iran over the new year but it comes as the country's divided political factions argue over how to respond.
"The immediate holding of free presidential and parliamentary elections -- of course without their being engineered by the Guardian Council and without interference by military or security bodies so that people have a free choice -- is an urgent necessity," he wrote.
The Guardian Council is a powerful vetting body which oversees all elections in Iran and which barred Ahmadinejad among others from running for president last May.
The former president referred directly to a speech Khamenei delivered on Sunday in which he said that progress was needed in "the field of justice", acknowledging widespread criticism of the system.
"These clear comments from the leader can of course be understood" as an appeal for "urgent and concrete reforms that meet the demands of the people," he said.
Ahmadinejad called for the dismissal of judiciary chief Ayatollah Sadeq Larijani, a rival hardliner, on the grounds that the "injustices" of the judiciary were "one of the main causes of public discontent."
He also called for the release of all people arrested for criticising the regime and the halting of any proceedings under way.
Ahmadinejad remains popular, particularly among poorer segments of society who recall the large-scale welfare schemes he implemented during his 2005-2013 presidency.
But he has fallen out with the establishment, especially since he ran for president last year against Khamenei's advice.
A number of his senior aides have been arrested on financial and corruption charges, and his protege Hamid Baghaie was sentenced to 15 years in December.
The demonstrations over the new year, during which at least 25 people died, initially focused on economic problems but swiftly escalated into protests against corruption and the regime itself.
During the 2009 protests against Ahmadinejad's re-election, dozens of people were killed as the regime deployed militia to back up police.
Thousands of people were detained and his two reformist challengers -- Mehdi Karoubi and Mir Hossein Mousavi -- remain under house arrest.
