Stumbled across this at davidbowie.com. It is allegedly Nick Clegg aged 22 dressed as David Bowie in his Ziggy Stardust persona. The resemblance is not very good, either to Ziggy or Nick Clegg. He looks more like some plonker in a cheap party wig from the £1 shop who's been mucking about with his little sister's face paint set.
No doubt yet more embarassing details and/or pictures of Clegg will emerge now that everyone knows who he is.
