Time for the launch of Groupthink’s first competition, and this one’s going to be interesting.

With the Coalition seriously lagging behind the government in poll after poll, and with constant white-anting of leader Malcolm Turnbull within his own party, it’s a reasonably safe bet that Turbull will never be Prime Minister of this country. Not only will it take a miracle for the coalition to win in 2010, it will take a Herculean effort from Malcy to remain Opposition leader until 2013. So with that in mind, Groupthink has opened a Book and it’s time for you to take a punt: on what date will Malcolm Turnbull lose the leadership of the federal opposition?

Place your bet in the comments of this post, ensuring that you nominate a full date: day, month and year. For bonus points, also nominate the person you think will take over as leader upon Malcolm’s departure. The eventual winner will win something that will be determined at the time of the winning. A mystery prize, if you will.

Have at it!
