Labor is heading for an election loss, with support for Kevin Rudd plummeting to new lows, the latest Newspoll shows.
The prime minister is in a worse position now than when he was dumped as Labor leader in 2010, while Opposition Leader Tony Abbott's popularity is climbing.
The Newspoll, conducted for The Australian on the weekend, shows Labor's primary vote is just 34 per cent, compared to the coalition's primary vote of 47 per cent.
Primary support for the Greens has dropped from 11 per cent to nine per cent.
On a two-party-preferred basis, Labor's support stands at 46 per cent - a drop of two percentage points - while the coalition's support has risen to 54 per cent.
