Charles Grey, 2nd Earl Grey, known as Viscount Howick between 1806 and 1807, was a British Whig politician who served as Prime Minister of the United Kingdom from 1830 to 1834. He was a descendant of the House of Grey and the namesake of Earl Grey tea. Grey was a long-time leader of multiple reform movements. During his time as prime minister, his government brought about two notable reforms. The Reform Act 1832 enacted parliamentary reform, greatly increasing the electorate of the House of Commons.
