Supporters of president Mahmoud Ahmadinejad have been reduced to a small fraction in Iran's legislature, outnumbered by the conservatives who once backed him but then turned against him after he was perceived to challenge the authority of top clerics, according to final results from a run-off parliamentary election announced.
Iran has touted the turnout for Friday's vote as a show of support for the country's religious leadership in their confrontation with the West over Tehran's controversial nuclear programme.
The result is also a new humiliation for Mr Ahmadinejad, whose political decline started last year with his bold but failed challenge of Supreme Leader Ayatollah Ali Khamenei over the choice of intelligence chief.
While usually in agreement with the conservatives on foreign policy and many other issues, he had tried to change the rules of the political game in the Islamic Republic, where the president and legislature are subordinate to religious figures like Khamenei.
Mr Ahmadinejad's opponents had already won an outright majority in the 290-member legislature in the first round of voting in March. Of 65 seats for grabs in Friday's runoff election, Mr Ahmadinejad's opponents won 41 while the president's supporters got only 13 seats. Independents won 11, according to the semi-official Mehr news agency today.
The president's supporters had their best showing in the capital Tehran. Mr Ahmadinejad's conservatives critics won 16 seats while his supporters nine. Iran's major reformist parties, who oppose both Mr Ahmadinejad and the conservatives, mostly did not field candidates.
The new parliament will begin its sessions in late May. It has no direct control over key foreign and security policy matters like Iran's nuclear programme, but it can influence those issues and economic policies as well as the run-up to the election of Ahmadinejad's successor.
The results suggest Ahmadinejad will face a more belligerent parliament in the remaining time of his second four-year term in office that ends in August 2013. His allies are likely to be ousted from key posts, and his plan to cut economic subsidies challenged.
Iran's media has claimed that the turnout matched that of the initial round of voting on March 2, when 64% of voters reportedly cast ballots.
Iranian leaders have showcased the high voter turnout as a sign of trust in the clerical-led system and rejection of Western pressure over the nuclear issue. The West suspects Iran is pursuing nuclear weapons and is demanding that Iran stop uranium enrichment. Iran has refused, saying it is aimed at power generation and cancer treatment.
