John Stuart, 3rd Earl of Bute served as Prime Minister of Great Britain during 1762–1763. He resigned following fierce criticism of his signing of the Treaty of Paris with its perceived lenient terms for France and Spain despite Britain's successes in the Seven Years' War. The Bute ministry was made up largely of the same members as its successor, the Grenville ministry. George III favoured Bute, but could not keep him in government.
