…………………..

Well, it’s on. Again. As in, again, again.

Prime Minister Julia Gillard has just appeared live on Sky News. And by golly, she’s offered up some fighting words.

The Prime Minister has thrown down the gauntlet for Kevin Rudd to actually put his name forward in a ballot and to end the leadership speculation that has been plaguing the Labor Party for three years.

Gillard has called on any candidate for the role of Labor Party Leader (and quite possibly our next Prime Minister) to commit that they will quit politics forever, if unsuccessful in the ballot, which will take place tonight.

When pushed by interviewer David Spears, Gillard confirmed that she will not contest her Victorian seat of Lalor at the next election if she is unsuccessful in this evening’s caucus vote.

“If you win you are Labor leader. If you lose you will leave politics” said Gillard, as she laid down a final and official challenge to her detractors and put forward an ultimatum that was clearly directed at Kevin Rudd.

“I’m not interested in public accolades, I’m not interested in applause, I’m not interested in any of that personality politics,” Gillard said. “I came into politics to make a difference.”

So – despite there being NO formal challenger to her leadership at this stage, Julia Gillard says she will call a ballot for the Labor leadership at 7.00pm tonight.

And now? We wait.

The seemingly endless speculation about the Labor leadership will finally end this evening.

According to The Guardian Australia’s Lenore Taylor, a petition began circulating amongst Labor MPs to remove Julia Gillard as leader late this morning. The Prime Minister told Skye News that she has not seen that petition, nor have her colleagues pressured her to step down. But has decided to call this ballot anyway.

This strategic move from Gillard echoes her smart politics during the previous ballot, where she called the vote on early in an effort to stop Kevin Rudd getting the numbers he needed to win.

Previously, Rudd has appeared reluctant to be part of an outright challenge for the position of leader. This has left a big question mark over Kevin Rudd’s willingness to actually stand for the job and has meant that potential new Rudd supporters have been very cautious about getting behind this push. After all, they don’t want to see another meeting like last time – where there was an election called for the position of leader and Kevin Rudd failed to nominate.

However most Labor insiders are currently saying that Kevin Rudd will have the 53 votes he needs to become leader of the Labor Party once again – IF he decides to stand. It is understood that enough Gillard supporters have switched sides from the last time this whole debacle happened, to make Rudd leader once more.

It was confirmed this morning that rumours the Prime Minister would require a show of hands in any leadership ballot were not true. This means that Labor caucus members will take part in a secret ballot, allowing key members to switch their allegiances without fear of political retribution from factional heavyweights and union leaders.

Earlier today, key independent Tony Windsor said that he would withdraw his support for Labor if there was a change of leadership, and would vote in favour of a ‘no confidence’ motion in the Government. In those circumstances, Windsor would likely support Tony Abbott and the Coalition to form Government. However another independent, Bob Katter has said he would support a Labor Government led by Kevin Rudd.
