Australia's Foreign Minister Kevin Rudd resigned on Wednesday, reportedly over a leadership tussle over Prime Minister Julia Gillard.

The resignation came in the aftermath of the ongoing leadership tussle between Julia Gillard and Kevin Rudd in the Labour Party. Gillard ousted Rudd from the top post of the country in June, 2010.

Surprisingly, the announcement was made in Washington DC, during an official visit.

"The simple truth is that I cannot continue to serve as foreign minister if I don't have Prime Minister Gillard's support," the BBC quoted Kevin Rudd as saying at a press conference in the U.S. on late Tuesday night, which was telecast live in Australia.

"I therefore believe the only honourable course of action is for me to resign," he added.

However, Rudd did not give any indication on his future course of action, but mentioned that he would take a decision before parliament convenes on Monday.
