Support for Pauline Hanson’s One Nation party has risen fourfold since the election, says Newspoll.

Its support is not far below the Greens:

Newspoll surveys taken exclusively for The Australian since the July 2 election reveal support in the House of Representatives for One Nation has climbed to 6 per cent, up from 1.3 per cent on polling day.

One Nation appears to have made its gains over the past four months from other minor parties and independents, as well as ­taking a slice of support from the Turnbull government.

If this support is maintained, Hanson's party will be to the Liberals what the Greens are to Labor. A vacuum is being filled.
