Having announced his retirement on January 20, Sir Robert Menzies officially departed the prime ministership on this day in 1966. Harold Holt’s first ministry was sworn in at the same time.
It was a historic moment 50 years ago that brought to an end the political career of Australia’s longest-serving prime minister. Menzies had been Prime Minister for two years between April 1939 and August 1941. He formed the Liberal Party in 1944 and served for six years as Opposition Leader before defeating the Chifley Labor government in December 1949.
Menzies went on to win six more elections in 1951, 1954, 1955, 1958, 1961 and 1963. When he retired, he had been prime minister for 16 years and 5 weeks.
Harold Holt took office at the age of 57 with a ministerial career that had started 26 years earlier. He had first served under Menzies in 1940 and had been Treasurer since 1958.
