About Rab Butler

Richard Austen Butler, Baron Butler of Saffron Walden, also known as R. A. Butler and familiarly known from his initials as Rab, was a prominent British Conservative Party politician; he was effectively deputy prime minister to Anthony Eden and Harold Macmillan, although he held the official title for only a brief period in 1962–63. He was one of his party's leaders in promoting the post-war consensus through which the major parties largely agreed on the main points of domestic policy until the 1970s; it is sometimes known as "Butskellism" from a fusion of his name with that of his Labour counterpart, Hugh Gaitskell.
