The first hint that something was amiss came in a letter.
On November 4, guests at Riyadh’s Ritz Carlton were notified by the opulent hotel that: “Due to unforeseen booking by local authorities which requires an elevated level of security, we are unable to accommodate guests ... until normal operations are restored.”
The purge was already under way. Within hours security forces had rounded up dozens of members of Saudi Arabia’s political and business elite, mostly in the capital and the coastal city of Jeddah. Among them were 11 princes as well as ministers and wealthy tycoons.
Some were invited to meetings where they were detained. Others were arrested at their homes and flown to Riyadh or driven to the Ritz Carlton, which has been turned into a temporary prison.
The detainees were allowed a single, brief phone call home, a person familiar with the arrests told Reuters.
“They don’t receive calls and are kept under tight security. No one can go in or out,” the insider said. “It is obvious that there was a lot of preparation for it.”
The purge was ordered by 32-year-old Crown Prince Mohammed bin Salman. Officially next in line to the throne to his father, King Salman, he is now in effect running the country which he has said he will transform into a modern state.
To do that - and in an attempt to shore up his own power - he has decided to go after the Saudi elite, including some members of the royal family, on accusations such as taking bribes and inflating the cost of business projects. Those arrested could not be reached for comment.
At stake is political stability in the world’s largest oil producer. The Crown Prince’s ability to rule unchallenged depends on whether the purge is successful.
The Crown Prince believes that unless the country changes, the economy will sink into a crisis that could fan unrest. That could threaten the royal family and weaken the country in its regional rivalry with Iran.
Prince Mohammed decided to move on his family, the person familiar with events said, when he realised more relatives opposed him becoming king than he had thought.
“The signal was that anyone wavering in their support should watch out,” said the person familiar with the events. “The whole idea of the anti-corruption campaign was targeted towards the family. The rest is window dressing.”
King Salman said the purge was in response to “exploitation by some of the weak souls who have put their own interests above the public interest, in order to, illicitly, accrue money”. Insiders said the accusations were based on evidence gathered by the intelligence service.
Government backers have rejected suggestions that the campaign is really about eliminating political enemies. There was no immediate comment from the royal court on this story.
Among those now holed up at the Ritz Carlton hotel is Prince Miteb bin Abdullah, who is head of the powerful National Guard and Prince Mohammed’s cousin.
Miteb was in his farm house in Riyadh when he was called to a meeting with the Crown Prince. Such an invitation, even at night, would not be unusual for a senior official and would not have aroused suspicion.
“He went to the meeting and never came back,” said a second insider who has connections to some of those who were detained.
Others held include Prince Alwaleed bin Talal, who is chairman of international investment firm Kingdom Holding and a cousin of Prince Mohammed, and Prince Turki bin Abdullah, former governor of Riyadh province and a son of the late King Abdullah.
