Whitlam served as an air navigator in the Royal Australian Air Force for four years during World War II, and worked as a barrister following the war. He was first elected to Parliament in 1952, representing Werriwa in the House of Representatives. Whitlam became Deputy Leader of the Labor Party in 1960, and in 1967, after the retirement of Arthur Calwell, was elected Leader and became the Leader of the Opposition. After narrowly losing the 1969 election, Whitlam led Labor to victory at the 1972 election after 23 years of continuous Liberal-Country Coalition Government.
