Iranian President Mahmoud Ahmadinejad warned the United States and Britain Sunday to stop meddling in Iran's internal affairs, the ISNA news agency reported.
"Definitely by hasty remarks you will not be placed in the circle of friendship with the Iranian nation. Therefore I advise you to correct your interfering stances," Ahmadinejad was quoted as saying.
"They (Western countries) want to portray as small the great and powerful position that has been created for the Iranian nation inside and outside after the recent election, by which of course they made a mistake and they showed they still do not know the Iranian nation," Ahmadinejad said.
"Definitely recent events will add to the Islamic Republic of Iran's greatness and might," he said.
Iranian officials said Sunday they will announce the results of their investigation of complaints related to the disputed election by the end of the week, Reuters reported.
Foreign Minister Manoucher Mottaki said the "possibility of organized and comprehensive disruption and irregularities in the election ... is almost close to zero."
"They (officials) are looking into the complaints and by the end of the week, when the investigations come to an end, the result will be announced regarding the latest election," he said.
Mottaki held a news conference where he rebuked Britain, France and Germany for raising questions about reports of voting irregularities in hardline President Mahmoud Ahmadinejad's re-election — a proclaimed victory which has touched off Iran's most serious internal conflict since the 1979 Islamic Revolution.
He criticized Britain, France and Germany for raising questions about Ahmadinejad's victory. Mottaki accused France of taking "treacherous and unjust approaches" and said Britain "has always created problems" in relations.
Britain's Foreign Secretary David Miliband strongly denied the allegations, saying he "categorically" rejects the idea that Iranian protesters are being manipulated by foreign countries.
Miliband said the claims of interference were "without foundation." He said it was up to the Iranian people to choose their government.
State radio reported Iran's parliament speaker Ali Larijani echoed Mottaki's remarks, calling for Iranian ties with the U.S., Britain, France and Germany to be reconsidered.
"He called the stances of the United States, Britain, Germany and France towards Iran's presidential election shameful and called on parliament's foreign and security policy commission to put the reconsideration of ties with the three European countries on its agenda," the state radio report said.
