King Abdullah's son Mutaib?

"... But the Saudi king’s move may be construed as an attempt to clear a path to the throne for his son Mutaib, currently the commander of the National Guard.The famous Twitter activist @mujtahidd told Al-Akhbar, “Abdullah is seeking to put his son Mutaib on the throne. If he waits for the long line of Abdul-Aziz’s sons [to pass], then his son will never reach the throne. But the king wants his son to take the crown while he is still alive.”@mujtahidd added, “Muqrin has two characteristics that allow the king to exploit him to get what he wants. First, he is the youngest and last son of Abdul-Aziz. Second, he is extremely weak-willed to the extent that he perceives his brothers as his masters, because his mother was a black slave.”
Concerning the timing of the announcement, @mujtahidd said, “Abdullah wanted to appoint him now because, in a while, it will become unequivocally clear that Salman’s Alzheimer’s will force his departure, after which Muqrin would be appointed as the crown prince. The king will then appoint his son Mutaib as his second deputy.”..."
