I appreciate that your question is genuine but if anyone has a hope or expectation that some sort of government criteria is that the new owner can be a businessman, just not a Saudi Arabian one, then it is fantastical to say the least. I appreciate why a poster on the caf may say that there should be a ‘blanket ban on any private business’ - but it is not realistic for a potential buyer to fail a fit and proper test ‘because they are from Saudi’. It’s not even worth mentioning surely.
Imagine an open market with a policy of ‘no Saudis need apply’. There will/may be a ban on murderous regimes perhaps, but nobody will be banned simply because they are Saudi.
