David Anthony Llewellyn Owen, Baron Owen, CH, PC is a British politician, Chancellor of the University of Liverpool, and one of the founders of the British Social Democratic Party (SDP). He led the SDP from 1983 to 1987 and the re-formed SDP from 1988 to 1990. He is also known for becoming the youngest person in over forty years to hold the post of British Foreign Secretary (from 1977 to 1979) and as one of the authors of the failed Vance-Owen and Owen-Stoltenberg peace plans offered during the Bosnian War.
Owen had been long regarded as a serial resigner. He quit as Labour’s spokesman on Defence in 1972 in protest of the Labour Leader Harold Wilson’s attitude to the EEC. He left the Labour Shadow cabinet over the same issue later and over unilateral disarmament in November 1980 when Michael Foot became Labour leader. He resigned from the Labour Party when it rejected “one member, one vote” in February 1981. He resigned as Leader of the Social Democratic Party, which he helped to found when the party’s rank-and-file membership voted to merge with the Liberal Party.
