The relative youth and almost unprecedented power shared by the two heirs to the Saudi throne mean they are likely to dominate the kingdom's politics for decades, putting their pivotal relationship increasingly under scrutiny. Crown Prince Mohammed bin Nayef, 56, and Deputy Crown Prince Mohammed bin Salman, 30, are next in line to succeed 79-year-old King Salman in ruling the world's top oil exporter, as it faces regional turmoil and low crude oil prices. People who have attended meetings between the two cousins describe their public interactions as cordial and respectful, but such accounts have done little to stem suspicions among some Saudis that this apparently amicable facade hides a more fractious relationship. The elder prince, bin Nayef, is a widely respected veteran of Saudi politics, while the younger royal is a relatively inexperienced but favored son of the king. Although Saudis are well accustomed to factionalism among the Al Saud dynasty's hundreds of princes, several well-connected Saudis said the relationship between the two men was simply too sensitive a subject to discuss openly. However, some did acknowledge hearing about underlying friction, though they refused to be any more specific. Last week, the king removed Saad al-Jabri, an aide of the crown prince, from his role as a minister of state, a move that was not officially explained, and led to speculation among Saudis and Gulf-based diplomats that it reflected wider tension within the ruling elite. There was no official comment to explain his removal. Since he took power in January, Salman has overturned expectations of how the kingdom conducts its business, changing the line of succession, launching a military operation in Yemen and endorsing an oil strategy that has let prices fall. That new approach appears to owe much to the two Prince Mohammeds, who between them now control most levers of power via a pair of government supercommittees on security and the economy, while most other Al Saud members have been sidelined. Observers heralded a departure from the previous era to more pro-active policies after years of paralysis, citing the power of the princes. Dynastic politics The prominence of the two Prince Mohammeds means that any moves at the top of the Saudi government, particularly any involving Al Saud members or close aides to either of Salman's named successors, will be closely watched. The removal of Jabri, who even in 2006 was described by U.S. diplomats in a Riyadh embassy cable later released by WikiLeaks as Mohammed bin Nayef's "go to" man on a range of issues and a key member of the prince's staff, was just such an event. If the crown prince's other key aide, Khalid al-Humaidan, who was made intelligence chief in January, were replaced, for instance, then speculation about friction at the top, and rumors about new changes in the line of succession, might grow. Dynastic squabbling brought down a Saudi state in the 1880s. In the last century, King Saud's efforts to limit the line of succession to his own sons, cutting out brothers and nephews, contributed to the family forcing him from power in 1962, so such things are keenly watched. Tension between the family's different wings are usually open secrets, talked about in private and denied in public, while the Al Saud present an appearance of unity, an approach that has sometimes backfired by letting speculation flourish.
