LONDON — Saudi Arabia announced the arrest on Saturday night of the prominent billionaire investor Prince Alwaleed bin Talal, plus at least 10 other princes, four ministers and tens of former ministers.
The announcement of the arrests was made over Al Arabiya, the Saudi-owned satellite network whose broadcasts are officially approved. Prince Alwaleed’s arrest is sure to send shock waves both through the Kingdom and the world’s major financial centers.
He controls the investment firm Kingdom Holding and is one of the world’s richest men, with major stakes in News Corp, Time Warner, Citigroup, Twitter, Apple, Motorola and many other well-known companies. The prince also controls satellite television networks watched across the Arab world.
The sweeping campaign of arrests appears to be the latest move to consolidate the power of Crown Prince Mohammed bin Salman, the favorite son and top adviser of King Salman.
At 32, the crown prince is already the dominant voice in Saudi military, foreign, economic and social policies, stirring murmurs of discontent in the royal family that he has amassed too much personal power, and at a remarkably young age.
Before sparring with Mr. Trump, Prince Alwaleed was publicly rebuffed by Mayor Rudolph W. Giuliani, who rejected his $10 million donation for the victims of the Sept. 11 terrorist attacks in New York because the prince had also criticized American foreign policy.
As powerful as the billionaire is, he is something of an outsider within the royal family — not a dissident, but an unusually outspoken figure on a variety of issues. He openly supported women driving long before the kingdom said it would grant them the right to do so, and he has long employed women in his orbit.
In 2015 he pledged to donate his fortune of $32 billion to charity after his death. It was unclear Saturday whether Saudi Arabia’s corruption committee might seek to confiscate any of his assets.
Saudi Arabia is an executive monarchy without a written Constitution or independent government institutions like a Parliament or courts, so accusations of corruption are difficult to evaluate. The boundaries between the public funds and the wealth of the royal family are murky at best, and corruption, as other countries would describe it, is believed to be widespread.
The arrests came a few hours after the king replaced the minister in charge of the Saudi national guard, Prince Mutaib bin Abdullah, who controlled the last of the three Saudi armed forces not yet considered to be under control of the crown prince.
The king named Crown Prince Mohammed the minister of defense in 2015. Earlier this year, the king removed Prince Mohammed bin Nayef as head of the interior ministry, placing him under house arrest and extending the crown prince’s influence over the interior ministry’s troops, which act as a second armed force.
Rumors have swirled since then that King Salman and his favorite son would soon move against Prince Mutaib, commander of the third armed force and himself a former contender for the crown.
