There are claims New South Wales Nationals leader John Barilaro is undermining the Liberals' bid to win the Eden-Monaro by-election. Mr Barilaro and his supporters are reportedly asking voters to preference Labor ahead of Liberal candidate Fiona Kotvojs. The provocative tactic comes after Mr Barilaro left open the possibility of contesting Eden-Monaro at the next federal election. Under the Coalition agreement, he would be prevented from running against a sitting Liberal MP. Image: News Corp Australia
