The nation is screaming at Libs: Xenophon

Key independent senator Nick Xenophon has labelled the Liberal leadership crisis an embarrassing mess.

"And I think that the entire nation is fed up with it," he told reporters in Canberra on Sunday.

Liberal MPs will meet on Monday morning to vote on a motion to spill the party's leadership.

"It's as though they can't hear the rest of the nation screaming at what's going on," Senator Xenophon said, adding Australians had seen Labor tear itself apart and were now watching the Liberals do the same thing.

"This is no way to run a country."

Palmer United Party leader Clive Palmer described the saga as a storm in a tea cup.

"What's more important is not individuals, but getting this country going with the right policies," he told reporters.
