After several unsuccessful runs for preselection, Whitlam was elected in 1975 to the House of Representatives seat of Grayndler in central Sydney. His father Gough Whitlam was at that time the Leader of the Labor Party and had just been dismissed as Prime Minister by the Governor-General, Sir John Kerr. Labor was heavily defeated but Tony Whitlam easily won Grayndler. He became only the second federal MP to serve in the House at the same time as his father. He is also the only child of an Australian Prime Minister to be a federal MP (Kevin and Brendan Lyons, sons of Prime Minister Joseph Lyons, were Tasmanian state MPs).
