Mohammed Bin Nayef Bin Abdelaziz Al-Saud (MBN) is a nephew of King Salman and, like him, from the powerful Sudairi bloc that has re-emerged as the dominant branch of the Al-Saud in the months since King Abdullah’s death. Born in 1959, he has long been thought of as a contender for the throne, and has excellent dynastic credentials, having been born to two members of the Al-Saud, the late crown prince Nayef and Jawahar Bint Abdelaziz Bin Musaid Bin Jiluwi.
