This morning The Daily Telegraph splashed with a story that's been political gossip for months: Barnaby Joyce's ex-staffer and now-girlfriend is pregnant with his fifth child. This comes months after another story, which also ran on the front page, about the unspecified "personal crisis" that was spilling into the Deputy Prime Minister's public life in the lead-up to the New England byelection.

The story has brought to the fore the age-old debate for political journalism: when is a politician's personal life in the public interest? So we did a whip around of some interested observers on the ethics of publishing this story.
