In Greek mythology, Prometheus was a Titan who deceived Zeus, King of the Gods, and stole fire for mankind. His punishment was to be chained to a mountain top and have his liver pecked out every day, by a visiting vulture or eagle. Generally, I steer away from classical references like this in my drawing but I felt that the mess that the Prime Minister is in over Northern Rock really deserved an unpleasant image and this is certainly one.

A potted history of Prometheus clipped from Wikipedia:

On Mount Caucasus, Prometheus was tormented day and night by a giant vulture tearing at his liver. By day, the eagle would come down to the cliff and devour Prometheus’ liver, and by night the liver would regenerate, only to have it destroyed the following day again.
