William Morris 'Billy' Hughes, CH, KC (25 September, 1862 – 28 October, 1952), Australian politician, was the seventh Prime Minister of Australia, the longest-serving member of the Australian Parliament, and one of the most colourful figures in Australian political history. Over the course of his 51 year federal parliamentary career (and an additional 7 prior to that in a colonial parliament), Hughes changed parties five times: from Labor to National Labor to Nationalist to Australian to United Australia to Liberal, was expelled from three, and represented four different electorates in two states.
