President Bush is to make a state visit to Britain in November according to anti-war protesters who promise the US leader a hot reception.
Buckingham Palace is expected to make an official announcement about the four-day full ceremonial visit on Tuesday, according to the Stop the War Coalition.
Tony Benn, a vcritic of the war in Iraq, said the people of Britain would be outraged by the news.
"President Bush will not be welcome in Britain. His war has killed thousands of people and left Iraq in chaos and now Iraq's assets are to be sold off on the world market," he said.
"I hope that when he comes public opinion will express itself against those policies again."
The Stop The War Coalition says it will organise huge protests against Mr Bush's presence on British soil.
Spokesman John Rees said: "The Blair government is adding insult to injury by extending this invitation to George Bush.
"The majority of people in this country believe there was no justification for this war with, Iraq but now their taxes will pay for the war-monger-in-chief to be treated like some sort of British war hero.
"We will mobilise protests which I believe will have the potential to rival our largest previous protests."
A Buckingham Palace spokesman refused to confirm or deny the reports of a visit by President Bush. Any visit would only be staged following advice from the government.
