The ALP had been out of office since the Chifley Government's defeat in 1949 and, since 1951, had been under the leadership of Bert Evatt, whom Whitlam greatly admired. In 1954, the ALP seemed likely to return to power. The Prime Minister, Robert Menzies, adroitly used the defection of a Soviet official to his advantage, and his coalition of the Liberal and Country parties was returned in the 1954 election with a seven-seat majority. After the election, Evatt attempted to purge the party of industrial groupers, who had long dissented from party policy, and who were predominantly Catholic and anti-communist. The ensuing division in the ALP, which came to be known as "The Split", sparked the birth of the Democratic Labor Party (DLP). It was a conflict that helped to keep Labor out of power for a generation, since DLP supporters chose the Liberal Party in preferential voting. Whitlam supported Evatt throughout this period.
