Tony Blair today admitted he was rubbish at science when a schoolboy at Fettes college.
In the spirit that confession is good for the soul, we asked the other party leaders what was their achilles heel at school.
Sir Menzies Campbell, a world-class sprinter who competed in the 1964 Tokyo Olympics, confessed: "I've always said I spent more time on the running track than in the classroom."
Alex Salmond, leader of the Scottish Nationalists, was less modest: "I was great at science, loved history (that's probably why I ended up as an economist) but disastrous at technical drawing. I was the only pupil in the history of Linlithgow Academy to fail at technical drawing."
A spokeswoman for David Cameron - giving a speech in Wales today - admitted: "I don't think he was brilliant at science at school either."
Yet another spooky simililarity between the two men?
