Question: How old was Gough Whitlam the year that Monro re-entered parliament as the Liberal member for the new seat of Sutherland? Passage:After two unsuccessful attempts, Monro was elected to the New South Wales Parliament as the United Australia Party member for Georges River. He defeated the sitting Labor member Ted Kinsella at the 1932 landslide that swept away the government of Jack Lang. Monro retained the seat until the 1941 election, when his defeat by Labor's Arthur Williams contributed to the fall of the conservative coalition government of Bertram Stevens. Monro re-entered parliament as the Liberal member for the new seat of Sutherland at the 1950 state election. In a result which had a major influence on the course of Australian history, he defeated the Labor candidate Gough Whitlam. Whitlam subsequently turned his attention to Federal politics and became the Prime Minister of Australia between 1972 and 1975. Monro was defeated at the next election in 1953 and retired from public life. He did not hold a ministerial, party or parliamentary position.
