Jonathan Guinness, 3rd Baron Moyne, a British peer, merchant banker and writer who served in the House of Lords from 1992 to 1999, died October 30, 2026, aged 96.
Born in London on March 16, 1930, he was the elder of two sons of Bryan Guinness, 2nd Baron Moyne, and Diana Mitford, later known as Lady Mosley. A member of the Guinness family, he was educated at Eton College and the University of Oxford.
He began his working life as a journalist before moving into merchant banking, joining Messrs Leopold Joseph. He also served as a non-executive director of Guinness plc, a position he held until retirement. His public service included membership of Leicestershire County Council from 1970 to 1974. A Conservative, he contested two parliamentary by-elections without success: Lincoln in 1973 and Coventry North West in 1976. The Lincoln contest was notable for the election of Dick Taverne. Guinness’s career brought together business, local government and parliamentary politics, alongside his work as a writer. His House of Lords service came later, from 1992 until 1999.
