King Salman’s reign of four months has brought dramatic changes to Saudi Arabia’s succession framework. Prince Muqrin was appointed as heir before being relieved of his duties in favor of Prince Mohammed bin Nayef, and Prince Mohammed bin Salman (MBS) was designated as heir to the heir. A son of the monarch, MBS carries a variety of additional portfolios, including that of minister of defense and chairman of the Council of Economic and Development Affairs (CEDA), which makes policy on non-security matters. MBS is also a member of the Council of Political and Security Affairs (CPSA), and as a result is the only royal sitting on both the CEDA and CPSA. The monarch’s son added another portfolio to his growing constellation as well: head of a new 10-member supreme council for the state-run oil company, Saudi Aramco. However, MBS surrendered his duties as head of the Royal Court to his deputy, Hamad bin Abdulaziz al-Suwailem, a longtime aide to the king.
