September 30-October 4, 2001: British Prime Minister Tony Blair Claims Seeing ‘Incontrovertible Evidence’ that Bin Laden Is Responsible for 9/11

British Prime Minister Tony Blair says, “I have seen absolutely powerful incontrovertible evidence of [Osama bin Laden’s] link to the events of the 11th of September.” However, he says that because “much of this evidence comes to us from sensitive sources, from intelligence sources,” there is a question over how much of it can be made public. [BBC, 9/30/2001; Daily Telegraph, 10/1/2001] Three days later, the two British opposition leaders meet for a 45-minute confidential briefing with Blair, where he shows them this evidence. Following this briefing, Liberal Democrat leader Charles Kennedy says he now accepts there is “compelling evidence” of Bin Laden’s guilt. [Daily Telegraph, 10/4/2001; Guardian, 10/4/2001] Blair refers to the evidence he has seen on October 4, 2001, when he presents to Parliament a paper indicating that al-Qaeda is responsible for 9/11 (see October 4, 2001), but again he says that because of sensitivity issues, “It is not possible without compromising people or security to release precise details.” [CNN, 10/4/2001]
