The spill is definitely on for Tuesday, as WA MP Luke Simpkins announced that he would challenge the PM.

While Simpkins couldn't win, it means the position would become vacant. Julie Bishop could put up her hand, because she said only that she wouldn't challenge Abbott, not that she wouldn't contest the leadership if it became vacant.

All the money's on Malcolm Turnbull, of course, and he looks as if he's trying very hard not to smirk. I'd have welcomed it at one time, but that was before he sold out on climate change, trashed the NBN scheme, and cut the ABC into little pieces. Now – not so much.

Mostly, I'm looking forward to seeing the look on Abbott's face when it's over. If he'd any sense at all, he'd have called the spill himself so he could at least go out with some dignity. But he wouldn't understand that concept.
