IMO the idea of having a 'peoples' statue in Trafalgar Square is a nice one. There are too many statues of nobles and warmongers. And Alison Lapper is extremely brave to sit naked and pregant for all to see in the middle of London :-)
But it is not the first statue of a disabled person in Trafalgar Square - for example, look above you to the top of Nelson's Column where you will see a guy with only one arm, who was blinded in one eye!!
