"Castlereagh, who had been often pointed out as the successor of Pitt, wanted the large views of that great man... [He] was an obscure orator, garnishing his speeches with confused metaphors... He had no classical quotations, no happy illustration, no historical examples... Yet his influence with his party was very great, and he was, till near the close of his life, a successful leader of the House of Commons. For this end he possessed...very considerable advantages. He was, as a man of business, clear, diligent, and decided. His temper was admirable – bold and calm, good humoured and dispassionate. He was a thorough gentleman; courteous, jealous of his own honour, but full of regard for the feelings of others. No one doubted his personal integrity, however much they might dislike his policy."
