He’s pushed through reforms but some fear there is a darker desire driving the ruler. In one night, Crown Prince Mohammad bin Salman arrested over a dozen Princes and government ministers on corruption charges. To turn on his own royal family, he must be serious. But is corruption the Crown Prince’s real target or is this a power grab?
