Carol Vorderman always seemed quite pleasant on Countdown so I was a little surprised that she was such a Daily Mail shrew on Question Time last night. She may be good at counting but she just came across as a bit dim. On Twitter she was being compared to Sarah Palin. Will Self was his usual withering, caustic self, completely highlighting Vorderman's lack of much intellect. She looked great though - but I'm sure there has been a little Botox.
