And here is this from the Stop the War site, dated September 25th:

Confirmed - George W Bush to visit Britain!

It has been confirmed by Buckingham Palace that George W Bush will be visiting Britain on the 19th, 20th and 21st of November. This will be a state visit.

People will be outraged at this fêting of the warmonger in chief even as Iraqis are dying daily. The Stop the War Coalition will be organising demonstrations and a number of other events and stunts on every day of his visit to make it clear that he is not welcome here. Put the dates in your diary now!

We have produced a letter demanding that the British Government retract this invitation immediately. This letter will be available at the demonstration this Saturday and will also be available from the office and on the website. We want people to sign it and send it to 10 Downing St.

Let's make it clear to this government that George W Bush is not welcome here and that if he does come, he will get a reception he will never forget.

See you all on Saturday!
