No date, no timeline, but Costello will be neither deputy nor leader of the Liberals in opposition.
Costello won't lead ...
Never saw that coming.
On second thought, we did see it coming, didn't we?
This explains why Costello didn't challenge Howard. He and his family had already made a decision, perhaps? He'd had enough, they'd had enough? Good for him.
So much for the critics in their easy chairs claiming that Costello was too spineless to challenge.
It's not gutless if you don't want the job folks.
