Educated at Eton from 1758 until 1765, he became a Lieutenant in the Royal Navy and an M.P. for Inverness in 1774. In 1780 he became notorious for his involvement with the "No Popery" riots in London, for which he was tried but acquitted on the charge of 'constructive' treason. In 1786 he became a Jew and died unmarried of gaol fever in Newgate prison, on 1 November 1793, while serving a sentence of five years' imprisonment for libel.
