Spencer Perceval (1762–1812): Chancellor of the Exchequer 1807–1812, and Prime Minister 1809–1812. Southey admired Perceval’s opposition to Catholic Emancipation and Perceval was reported to be impressed by Southey’s attacks on Methodism. Perceval’s assassination in 1812 deeply shocked Southey, as it seemed to reveal popular sympathy with Perceval’s killer and to weaken the government’s hostility to Catholic Emancipation.
