---The parliament introduced an emergency bill to go to a vote on Sunday on the issue, said the website of IRIB television.

Several politicians cried "Death to Britain" as the measure was adopted with 162 votes. Five deputies voted against.

The wording of the bill was not immediately divulged.

But the head of the parliamentary committee on foreign policy and national security, Alaeddin Boroujerdi, said he was asking the foreign ministry "to expel the British ambassador from the country," said the parliamentary website.

Britain on Monday, in co-ordination with the United States and Canada, announced new sanctions on Iran over its nuclear programme, after a report by the UN atomic energy watchdog this month suggesting Tehran was researching nuclear weapons.

Britain, which hosts the world's biggest financial market in the City of London, said it was "ceasing all contact" between its financial system and that of Iran.

Britain and Canada have embassies in Tehran. The United States does not, having closed it after Islamic students took its diplomats hostage in 1979 following Iran's revolution.

China said new sanctions unveiled by Western states against Iran over its nuclear programme would not resolve the issue but would instead "exacerbate" the situation.

"We believe pressuring and sanctions cannot fundamentally solve the Iranian nuclear issue. On the contrary, they will complicate and exacerbate the issue and intensify confrontation," said foreign ministry spokesman Liu Weimin.

China is a key ally of Iran. They have become major economic partners in recent years, thanks partly to the withdrawal of Western companies in line with sanctions against the Islamic republic.

Iran's other ally Russia – which, along with China, blocked any possibility of the new sanctions being put to the UN Security Council for wider adoption – has called the Western measures "unacceptable and against international law".---

Relations between the UK and Iran have been extremely low these past decades following many incidents such as the siege of the Iranian embassy in London in 1980, the fatwa issued by the Iranian supreme leader Ayatollah Khomeini on British author Salman Rushdie in 1989 and the seizure of royal navy personnel in 2007 among others.

With such tensions escalating ever more abruptly each year, the West's outright refusal to let the Islamic theocracy gain access to nuclear weapons and the stubborn perseverance of Iran in pursuing its nuclear project no matter what, it seems like the question is not if there will be a war, but rather when.
