It has now been reported that the question and details about Rudd were fed to Farage by none other than the current CEO of Sky News Australia, on request of the former CEO of Sky News Australia who now runs GB News, the network that employs Farage.
I'd be highly surprised if Farage would have even thought to bring this up otherwise.
I think he's right that Rudd is nasty 😆 I have my doubts that he "heard" it from anyone, though, or that he knew anything about Rudd until Farage read him that tweet.
It's obvious he has no idea who Rudd is, he was just going off Farage's suggestion. I guess the real news is that Rudd apparently pissed off all the right people.
