Some of the numbers being thrown around are laughable.
The family own 31.1% of the bank Arab Jordan Investment Bank according to a piece earlier in the thread.
There are 150,000,000 shares in AJIB with a current value of JOD1.78/share.
Total market capitalisation of AJIB: JOD267,000,000.
31.1% of JOD267,000,000 = JOD83,037,000.
JOD1 = GBP0.98
JOD83,037,000 = GBP 81,456,081

Translate above link to English and the family members showing as shareholders are: Abdulkadir Abdullah Ahmad Judge, Hani Abdel Qader Abdullah judge, Samer Abdul Kader Abdullah judge, Wael Abdul Qader Abdullah judge - those names give us a 30.19% stake in AJIB so the family stake in AJIB may be slightly less than calculated.
They've probably got other business interests but Sheik Mansour this is most definitely not.
