Come on Londoners – it’s judgement day! Now that the new designs for the Fourth Plinth are on display, I think it’s time for us all to have our shout about Thomas Schutte’s Model for a Hotel – that stack of neon plexiglass, to the north-west of Nelson’s column. Well – here’s my shout anyway: I think it’s a disgrace. Ken told us it would ‘sparkle through the months of winter and lift Londoners' spirits’. Cobblers. It sends my spirits creeping right down into my boots. Against anything but a bright blue sky, the acid yellow looks grubby and the poor thing is far, far too small for such a grand position. The Fourth Plinth is a space for dynamic, new art, it’s one of the most prestigious commissions in Europe, but – most damning of all – most people can’t work up the energy to criticise Model for Hotel. At least Marc Quinn’s pregnant Alison Lapper was controversial.
