UK, Iran order tit-for-tat diplomatic expulsions

LONDON (Reuters) - Britain said on Tuesday it was throwing out two Iranian diplomats in response to Tehran's expulsion of two British diplomats as relations hit a new low following Iran's disputed presidential election.

Iran accused the British diplomats of "activities incompatible with their diplomatic status", Prime Minister Gordon Brown's spokesman said. He rejected the charge -- often used to denote spying -- as baseless.

Iran has accused Britain of interfering in its internal affairs after the June 12 election that sparked demonstrations in which at least 17 people have been killed.

Official results handed hardline President Mahmoud Ahmadinejad a landslide victory, but defeated candidate Mirhossein Mousavi has alleged the vote was rigged.

"Iran yesterday took the unjustified step of expelling two British diplomats over allegations which are absolutely without foundation," Brown told parliament.

"In response to that action, we informed the Iranian ambassador today that we would expel two Iranian diplomats from their embassy in London," he said.

Diplomats have been given one week to leave on both sides, Brown's spokesman said. He would not give the rank of the diplomats involved.

Iranian Ambassador Rasoul Movahedian was called to the Foreign Office on Tuesday and told of the British decision by Peter Ricketts, a senior official, the spokesman said.
