Mayor of London Boris Johnson says the fourth plinth has become an important part of London's art scene:
"I am immensely proud to support the Fourth Plinth, which has become a must-see cultural attraction for London, one that underpins the capital's status as a great world city for art. Just a few minutes walk away from Trafalgar Square itself, this exhibition promises a fascinating journey through the work of some of the best international artists working today."
