St. James's Palace Stakes
Plenipotentiary and Glencoe were scheduled to meet again in the St. James's Palace Stakes at Royal Ascot, but Lord Jersey withdrew his colt and Plenipotentiary was allowed to walk over for the £850 prize money. One report claims that Plenipotentiary looked very unsteady on his feet when cantering over the course, but little attention was paid to this at the time.
