A page of Bill Gates's notes and doodles, which was wrongly attributed to Tony Blair after being left behind on the speakers' rostrum at the World Economic Forum in Davos over the weekend, has sparked a storm of controversy.

Graphologists quoted in The Times jumped on the notes, claiming that Blair, the supposed author, had "more than a hint of megalomania about him". A team of handwriting experts from The Independent said that the author "is not a natural leader" and is "not sure of his priorities".

However, a Downing Street spokesman stated that the notes "were in fact doodles made by Bill Gates".

"We look forward with amusement to explanations by a variety of psychologists and graphologists of how various characteristics ascribed to the prime minister on the basis of the doodles, such as 'struggling to concentrate', 'not a natural leader', 'struggling to keep control of a confusing world' and 'an unstable man who is feeling under enormous pressure', apply to Mr Gates."

Microsoft told vnunet.com that it is not commenting on the findings, since Gates's visit to Davos was a private matter on behalf of his personal philanthropic work.
