Barnaby Joyce could retake Nationals leadership on Monday, opponents say

David Littleproud could be clear to run for top job if Michael McCormack stood aside

Leadership rumblings in the Nationals are expected to come to a head on Monday, with opponents of Barnaby Joyce saying he could retake the top job.

The other most likely leadership contender, David Littleproud, has told colleagues that as deputy leader he cannot challenge Michael McCormack. But Littleproud could be clear to run if McCormack spilled his own leadership or chose not to stand again after a successful no-confidence motion in the Nationals party room.
