'''Dennis Herbert Leech''' (born 6 April 1943 in Sidmouth) is a British former racing driver. Most of his racing career was spent driving saloon cars, mainly as a privateer in the British Touring Car Championship. He also entered selected rounds of the British Formula One Championship between 1978 and 1980. His most competitive years in the BTCC came in the 1980s, where he was often a front runner in his Class A 3.5 litre Rover Vitesse. In 1987 he finished as runner-up in his class, finishing sixth overall in his ageing Rover.<ref>{{cite web |url=http://www.btcc.net/html/history_standings.php?season_id=30 |title=BTCC - 1987 Standings |accessdate=2009-12-01 |url-status=dead |archiveurl=https://web.archive.org/web/20110716071908/http://www.btcc.net/html/history_standings.php?season_id=30 |archivedate=16 July 2011 |df=dmy-all }} Official 1987 BTCC Standing</ref> His final year in the BTCC came in 1992, entering his own-built Ford Sierra.
