TEHRAN (Reuters/AFP) - Irans top legislative body confirmed on Monday the results of a disputed June 12 election, which was won by President Mahmoud Ahmadinejad, state broadcaster IRIB reported. The secretary of the Guardian Council in a letter to the interior minister announced the final decision of the Council and declares the approval of the accuracy of the results of ... the presidential election, IRIB said. The decision followed a partial recount of the election. Irans English-language Press TV television station said the recount of a random 10pc of the votes, which was carried out on Monday, had shown no irregularities. Defeated opposition candidate Mirhossein Mousavi had previously rejected the Councils offer of a partial recount, saying the vote was rigged in Ahmadinejads favour and that the whole election should be annulled. Official results of the election, released on June 13, sparked the most widespread street protests in Iran since the countrys 1979 Islamic revolution. Mousavi and two other defeated presidential candidates had submitted a total of 646 complaints about the election. But the Guardian Council said most of the complaints were not considered as election irregularities and that it had dismissed them after conducting precise and thorough studies of the election process. The council is a 12-man body, six senior clerics appointed by the Supreme Leader and six Islamic jurists, which must ensure all laws agree with Islamic Sharia law and Irans constitution. It also vets aspiring candidates for presidential elections. Meanwhile, Iran said on Monday five of the nine detained local staff at the British embassy in Tehran had been released while the other four were being held for questioning. Iranian media said on Sunday several local embassy staff had been held on accusations of involvement in the street protests that rocked Iran after a disputed June 12 presidential election. Out of nine people, five of them have been released and the rest are being interrogated, Foreign Ministry spokesman Hassan Qashqavi told a news conference in comments translated by Irans English-language Press TV. In London, British Prime Minister Gordon Brown condemned the Iranian authorities for detaining local embassy workers in Tehran. Speaking at a news conference in Downing Street, Brown said he was deeply disappointed. Irans action ... is unacceptable, unjustified, and without foundation, he told reporters. We are deeply disappointed that Iran has detained some of Britains staff in Iran, Brown said at a press conference. Some of them have now been released, but we must now see that the others are set free to resume their work. Irans actions, first the expulsion of two diplomats, and now the arrest of a number of our locally engaged staff, is unacceptable, unjustified, and without foundation. And we with our international partners will continue to make this clear to the Iranian regime. Speaking alongside Brown at a Downing Street press conference, European Commission chief Jose Manuel Barroso said: I would like to express my full solidarity with the United Kingdom. Intimidation and harassment are unacceptable and they will be met with a strong collective European response. On Sunday, British Foreign Secretary David Miliband demanded the release of all the staff held and said his European Union colleagues had agreed to a strong, collective response to any harassment and intimidation against EU missions. Iran has stepped up accusations that Western powers Britain and the US in particular are interfering in its internal affairs and fomenting post-election unrest. London and Washington have denied the allegations. Qashqavi said Miliband and Iranian Foreign Minister Manouchehr Mottaki had spoken on the phone on Sunday evening when Miliband stressed Britains intention was not to interfere in Irans internal affairs. Mottaki said that if they really prove this in practice ... this can be considered as a positive step, Qashqavi said. Irans Intelligence Minister Gholamhossein Mohseni-Ejei said on Sunday the British embassy had played a role in the unrest following this months election, including sending people among the protesters telling them what to do and what to chant. Ahmadinejad on Monday called for a probe into the death of Neda Agah-Soltan, a woman whose apparent killing by the forces during a protest rally in Tehran generated an international outcry. Neda became an icon for the opposition after an Internet video showing her final moments was seen around the world. Meanwhile, foreign ministry spokesman Hassan Ghashghavi told reporters on Monday that Iran has no current plans to close embassies or downgrade diplomatic ties with foreign nations, There is no plan at the moment to close any embassy or downgrade ties with them, Ghashghavi said at his weekly news conference when asked if Tehran planned to close the British embassy. Iran has arrested a number local British embassy staff, accusing them of being involved in the unrest that rocked the nation after the disputed re-election of Mahmoud Ahmadinejad.
