Australia's major political parties face a "huge amount of grievance" as a leading Liberal figure concedes his party's decade of flawed policies has helped fuel the rise of One Nation.
Polling from RedBridge Group and Accent Research shows Pauline Hanson's One Nation could win up to 59 lower house seats if a federal election were held today.
The result would leave Senator Hanson's anti-immigration party as the official opposition, reducing the coalition to a handful of seats and forcing Labor into minority government.
