Australian Prime Minister Kevin Rudd called a general election on Sunday for September 7, six weeks after he toppled former leader Julia Gillard in a party-room vote, ending a turbulent three years in power for the minority Labor government.

He announced the election date in an email to supporters.

Rudd, who was dumped by his centre-left party in June 2010, has generated a spike in public support since he returned but conservative opposition leader Tony Abbott is still favorite to win power.

Rudd's Labor government could fall with the loss of just one of the 150 seats in parliament. His government currently holds 71 seats, the opposition 72, with one Green and six independent cross benchers.

Abbott's opposition has promised to scrap a 30 percent tax on coal and iron ore mine profits, and scrap a A$24.15/metric ton carbon tax, if he wins power.
