Melbourne, Mar 9 : Australian Prime Minister Kevin Rudd is not known for using "colourful" language, but the global economic crisis seems to be enough to cause a slip of the tongue in even a mild-mannered leader.

The Prime Minister made the slip when explaining that current circumstances made it necessary to borrow to keep the wheels of the economy turning, but that created a political "shit storm".

Defending his Government''s decision to spend 42 billion dollars to save the nation's faltering economy, Rudd warned punters to expect a "political s---storm" during a pre-recorded interview on Channel 7's Sunday Night program that aired last night.

Rudd told the Seven Network that it was necessary to keep building long-term economic infrastructure even in the down times to keep the foundation for jobs in place.

But he noted it meant that opponents would then complain about governments going into debt, the Daily Telegraph reported.

"There's a very simple alternative here: You either sit back as government and do nothing and just wait for the free market to fix it all up or you step in and try to fill the breach for a temporary period," Rudd said.

Melbourne's Liberal Lord Mayor Robert Doyle said that the colourful language was no accident.

"I don't think he dropped it, I think it was a carefully scripted attempt to make himself appear human ... one of the lads," he said.

"The PM is very emotional about these job losses, I think it was just something that came out in the moment," Labor Senator Mark Arbib said. (ANI)
