The regent's hack [graphic].

"The Regent, scarcely caricatured, rides (right to left) a white horse with the (bloated) head of Sheridan, the flank being branded 'P R'. The horse walks along a cobbled street which is strewn with large stones on each of which is the head of a member of the Opposition. Sheridan says: "Never fear, my dear Master, I will carry you through this ugly road in safety--I'll hick all the vile stones aside that would impede your way, and your old Hack, Sherry, you will find able to support you to the last." On the stone under his hoof is the head of Grenville. Two others have already been kicked aside: (?) Holland, and, in the foreground, the Duke of Norfolk. Others (left to right) are: Buckingham (in spectacles) and Whitbread, Grey, Lord Temple, Moira, and Erskine. Others are not characterized. The street leads into 'Manchester Square', showing that the Prince is on his way to Hertford House."--British Museum online catalogue
