Davos doodles were not Blair, says No 10

At first sight, they looked like doodles that showed the writing was on the wall for Tony Blair. Graphologists and psychologists lined up to claim that the scribbles - found at a G8 press conference in Davos, Switzerland - show Mr Blair struggles to concentrate after years as Prime Minister and is no longer a natural leader.

Several newspapers, including the Evening Standard, Times, Mirror and Independent, last week reported the PM was responsible for the scrawls.

The stories appeared after No 10 refused to deny the initial report - but today a spokesman said it was time to refute the claim.

The main suspects for the writing are now billionaire Bill Gates and U2 frontman Bono.
