By the way, can we expect Gillard to be questioned like this?
UPDATE: After Senator Bill Heffanan referred to Julia Gillard as "barren" this was the ALP's response:
Today, Mr Rudd said the change in attitude marked Mr Howard poorly.
"I think the challenge lies with Mr Howard to do the right thing here," Mr Rudd said on ABC Radio.
"Mr Howard has the habit, in the past, of when these comments are made by various people on his frontbench or his backbench, just to say: 'Well, that's them, they've got their right to express their point of view, don't let it come crashing across my shores'
"I noticed yesterday, when he was first put this proposition about Bill Heffernan, there wasn't much action then. It was only when people across the country reacted.
"I actually see this as much more of a referendum on Mr Howard's character and how he handles these sorts of questions."
