John Stuart, 3rd Earl of Bute (1713-1792), was a Scottish nobleman who was tutor to the future George III, and was appointed Prime Minister in 1762 after George became king, but served only briefly. He was strongly resisted by the Whig faction, who suspected him of being a secret Jacobite, and vilified by John Wilkes, who spread rumours that he was having an affair with Augusta, Dowager Princess of Wales and mother of the king. After his resignation, he spent the rest of his life on his estate at Highcliffe near Christchurch in Dorset, where he studied botany and acted as a literary and artistic patron. His wife Mary was the daughter of Lady Mary Wortley Montagu; they had eleven children.
