On November 4, 2017, the Lebanese Prime Minister, Saad Hariri resigned from office whilst in Riyadh, blaming Iranian manipulation of events. A day later, a number of prominent members of the al-Saud royal family were arrested, along with around 200 leading members of the country’s business elite. On November 6, the Saudis claim that a missile was launched from Yemen and intercepted near the Riyadh airport. Over 3 days, the severity of the challenges facing Saudi Arabia in the coming years became visible for all to see. In charge of responding to the challenges is the Kingdom’s new crown prince, the 32 year old Mohammed bin Salman, essentially the power behind the throne. Known by ‘Saudi watchers’ as MbS, the son of King Salman was appointed to the office of crown prince in June 2017 and wasted little time in seeking to transform the Kingdom’s fortunes. The office of crown prince is not without challenges, as four of the last five crown princes of Saudi Arabia have failed to become King. Yet few expect such a fate to befall MbS as a consequence of the moves made to secure his position.
