Exclusive: Leaked polling shows ALP annihilation

EXCLUSIVE: Julia Gillard's leadership has been rocked by her party's own polling, which reveals Labor would be wiped out in half the states and territories at a federal election.

The internal Labor polling, leaked to Seven News shows Labor would be left with no seats in Queensland, the Northern Territory, Tasmania or Western Australia.

The secret Government polling shows Labor's two-party preferred vote in Queensland has collapsed from 45 percent at the 2010 election, to just 36.

While in Tasmania, home to the bellwether seats of Bass and Braddon, it's plummeted 17 points to 44.

The results are even worse than previous polls and make confronting reading for the senior ministers, federal executive members and state secretaries on its distribution list.

These people will ultimately make the final call on Julia Gillard's leadership, and sources now say that decision might come in September.
