President Bush decided last night to cancel his planned speech to Parliament during his state visit to Britain because he feared being heckled by anti-war MPs. Senior White House adviser Dr Harlan Ullman told the UK Mirror: “It would have been a great photo-opportunity. But they were fearful it would to turn into a spectacle.” The decision to abandon the speech came as extraordinary security measures are placing London under a state of virtual siege ahead of Bush’s arrival today.
