Australian PM Gillard calls for vote on leadership

CANBERRA (REUTERS) - Australian Prime Minister Julia Gillard called for a caucus vote on her leadership later on Wednesday, in a bid to end uncertainty over her job.

Supporters of former leader Kevin Rudd have begun moves to try to oust Ms Gillard less than three months before scheduled September elections, in a last-ditch move to try to turn around opinion polls showing the party on track for a massive defeat.

Ms Gillard said she would retire from politics if she lost the vote and called on anyone contesting the leadership to do the same.
