A significant security operation will be in place for George Bush's visit to the UK as he completes his 'farewell tour' of Europe, the Metropolitan Police have said.
Mr Bush has been visiting France, Germany and Italy this week and is due to fly into Heathrow for meetings with Prime Minister Gordon Brown and former premier Tony Blair and to take tea with the Queen over the next two days.
The Stop The War Coalition is planning to stage a series of protests in a bid to make its views known one last time before the leader leaves the world stage.
But Deputy Assistant Commissioner Chris Allison said the Met police's "significant" operation would see a thousand officers deployed on the streets of London on each day of the tour to maintain order.
Andrew Burgin, a spokesman for the pressure group, said: "We think Bush is a war criminal. Both Tony Blair and George Bush are responsible by duplicity and lying for an illegal invasion of Iraq.
"They are responsible for the deaths of hundreds of thousands, that's no small matter for the people of Iraq."
The President and his wife Barbara will have tea with the Queen and Duke of Edinburgh at Windsor Castle on Sunday afternoon.
Later they will have dinner with Mr Brown and his wife at 10 Downing Street.
Anti-war demonstrators plan to stage protests at Windsor Castle, Parliament Square and defy what they claim is a police ban and march past Downing Street.
