Baron Selsdon

Baron Selsdon, of Croydon in the County of Surrey, is a title in the Peerage of the United Kingdom.^[1] It was created on 14 January 1932 for the Conservative politician Sir William Mitchell-Thomson, 2nd Baronet. His son, the second Baron, was a successful racing driver, winning the 1949 24 Hours of Le Mans in the first Ferrari (although his codriver, Luigi Chinetti, actually drove for all but one half-hour). The titles were then held by the second Baron's only son, the third Baron, who succeeded in 1963. He was one of the ninety elected hereditary peers that remain in the House of Lords after the House of Lords Act of 1999, till 2021, when he was removed due to non-attendance, under the provisions of the House of Lords Reform Act 2014. Lord Selsdon sat on the Conservative benches. Since 2024, the titles are held by the third Baron's only son, the fourth Baron.
