The "sudden" you are referring to is that those interested have probably suspected it for years, but noone outside of financial circles gave a feck before he was heavily involved in the potential takeover of United. After he left his government roles he set up Al-Mirqab, his private investment firm. They haven't made their asset portfolio public but judging by reports over the years it seems he has invested a lot in real estate (plus the 1bn Heritage Oil case) among other things. He is also said to be running Precision Capital, a bank holding company, which, by the looks of it, are controlling close to 100bn worth of assets if not more.
He is featured prominently in the three Paper leaks where he is seemingly involved in heaps of offshore companies which are hard to estimate the true asset value.
Anyway, judging by your post history with the pure negativity towards anything involving the Qatar bid (not bothering to fact-check anything, the sudden and weird direct comparison to the Malaga situation etc.) and constant defence of the SJR & INEOS bid (even trying to joke about SJR's probable tax evasion tactics), I suspect no information they could realistically provide you with that counter the state-bid would be deemed acceptable to you.
