Malaysian Prime Minister Najib Razak has played a deft defensive game to keep his job in the face of what ought to be overwhelming forces to remove him. He has fired enemies, coopted others and muzzled the press. That leaves only a handful who may stand in his way including Zeti Akhtar Aziz, the central banker, who is said to be under enormous pressure but who has access to incriminating bank records on both Najib and his wife, Rosmah Mansor. The other is Ahmad Hamdan Dahlan, the chief of the Malaysian Anti-Corruption Commission, who has remained silent on which way the commission may go. There are rumors in Kuala Lumpur that he may be the next to get the boot.
