Benn, Tony (Anthony Wedgwood) 1925- . British Labour politician, formerly the leading figure on the party's left wing. He was minister of technology 1966-70 and of industry 1974-75, but his campaign against entry to the European Community led to his transfer to the Department of Energy 1975-79. He unsuccessfully contested Neil Kinnock for the party leadership 1988. Son of Lord Stansgate, a Labour peer, Benn succeeded his father 1960, though he never used his title and in 1963 was the first person to disclaim a title under the Peerage Act. In 1981 he challenged Denis Healey for the deputy leadership of the party and was so narrowly defeated that he established himself as the acknowledged leader of the left. His diaries (four volumes published to 1990) cover in enormous detail the events of the period.
