Unfortunately, his son Lachlan is said to be pretty much equivalent, which if true, means not much will change.
It'd be great if Lachy has been pulling a massive bait-and-switch on his dad, but that'll be the most laughably naïve hope I've had in a while.
A big twist could be that he actually does this but then goes back on it the moment the shock kills off his dad. Sweet, sweet, early inheritance. Very Murdochian. And forty more days of winter years of Fox being Fox for the rest of us.
