After the third successive defeat of his party in the 1959 general election, Hugh Gaitskell attempted to reformulate the original wording of Clause IV in the party's constitution, but proved unsuccessful. Some of the younger followers of Gaitskell, principally Roy Jenkins, Bill Rodgers and Shirley Williams, left the Labour Party in 1981 to found the Social Democratic Party, but the central objective of the Gaitskellites was eventually achieved by Tony Blair in his successful attempt to rewrite Clause IV in 1995.
