Honestly, hugely clever of course, and I like him on Newsnight or telly when they film him from the side but really - face on on Dragon's den, I can't help but think, no woman living who looked that quirky would ever ever EVER get a presenting job on telly.
Same goes for the ubiquitous Andrew Marr, nice guy but not the greatest look for telly! I don't think we should be looksist but I think people can be telegenic without being perfect!!!!!
