"Prince Nayef's rise in tune with Muslim Brotherhood's regional takeover"

Yet, it's from the unreliable Debka.

".... three reasons why the hardheaded Prince Nayef, may already have been chosen to step into the shoes of Sultan:
1.  Nayef has a solid record of suppressing domestic opposition with an iron fist, including the challenge posed by al Qaeda.
2.  He is a conservative in Saudi terms, meaning he is close to the clerical establishment.
 In all five Arab nations overtaken by uprisings, Tunisia, Egypt, Yemen, Syria and Libya, the Muslim clergy sided with the rebels against the regime. In Saudi Arabia, the imams are full partners with the royal rulers and will be especially supportive of Nayef.
3.  The frontrunner for Crown Prince also maintains cordial relations with foreign Muslim Brotherhood chapters. Since the Brothers appear to be on their way to power in the new societies thrown up by the Arab "spring" – a trend with which President Barack Obama sympathizes – Nayef is the right man at the right time to lead the oil kingdom into integration with the dominant trend.
Although the Saudi royal house is obsessively secretive about its internal affairs, it was obvious Wednesday, Oct. 19 that something momentous was happening.... The process was not as untroubled as the king had hoped.
Prince Talal bin Abdulaziz, Nayef's most vocal opponent was conspicuously absent from the crisis meeting as were representatives of the royal branches which had been dropped out of the line of succession.
Nayef's appointment will not be formally announced until after Sultan's state funeral next Tuesday – or even the customary 40 days of mourning. This will give his rivals time to jockey for position – either to thwart it or cozy up to the future king.
The next contest will occur when the Allegiance Council has to choose Nayef's successor as crown prince, or third in line to the throne..."
