What is the birthdate of this British politician and academic who represents the Liberal Democrats and who co-created the Social Democratic Party in 1981?
Social Democratic Party (UK, 1988) The Social Democratic Party (SDP) formed in 1988 was a political party in the United Kingdom led by David Owen which lasted for only two years. The party was formed as a result of the original Social Democratic Party, created in 1981 by the "Gang of Four" (Owen, Roy Jenkins, Bill Rodgers and Shirley Williams, all dissident Labour former ministers) voting to turn its electoral alliance with the Liberal Party into a full merger of the two parties. The new Social and Liberal Democrats (SLD) party thus gained all of the records and assets of the original SDP.
