SYDNEY (Reuters) - Voters began casting ballots in a Sydney by-election on Saturday that could determine the future of Australian Prime Minister Malcolm Turnbull, who is hoping to regain his parliamentary majority and safeguard his leadership.
The election campaign in the blue-ribbon Sydney seat of Bennelong has been bitterly fought between the centre-right government's candidate, former tennis star John Alexander, and the Labor opposition's Kristina Keneally, a high-profile former premier of New South Wales, Australia's most populous state.
