Keneally has uphill battle to win against Alexander in Bennelong

Voters are determining the fate of Turnbull government as well as their local representative in a traditionally Liberal seat

Kristina Keneally will be fighting an uphill battle to win Saturday's Bennelong byelection for Labor, facing a Liberal margin of 9.7%. Polls suggest the Liberal party's John Alexander is the favourite, but the seat is very much still in play.

Bennelong has historically favoured the Liberals. Labor famously won the seat from John Howard in 2007, but it has otherwise elected Liberals at every election since its creation in 1949.
