Mohammed Bin Salman, crown prince of Saudi Arabia>> From popular prince to virtual pariah in the space of one year. To the West, the kingdom's de facto ruler was the younger more moderate face of Saudi Arabia. But at the G20 summit in Argentina, many leaders made it clear they wouldn't meet him.
MBS, as he's known, was given the benefit of the doubt over his steering of the war in Yemen, the cutting of diplomatic ties with Qatar, and the prince's own crackdown on corruption. Which saw dozens of the members of the Saudi royal family and top business leaders detained at The Ritz Carlton in Riyadh.
But on October 2nd that patience was tested to the extreme when the Saudi journalist Jamal Khashoggi, a critic of the new heir's policies, entered this consulate here in Istanbul, never to be seen again. The murder of Jamal Khashoggi shocked the world. As a steady drip of gruesome details were leaked to the Turkish press, Western officials said the trail of blame led directly to the door of Prince Mohammed, a charge denied by Saudi Arabia.
>> We are with Saudi Arabia. We're staying with Saudi Arabia.>> President Trump stood by his ally. Overwhelmingly, US lawmakers did not.>> I think he's crazy. I think he is dangerous.>> Earlier in the year, I covered the sweeping social changes brought in by the prince. I joined women running groups.
>> We're here!>> Yes.>> Woo-hoo!>> Learner drivers, as the ban on women getting behind the wheel was lifted. And female filmmakers, as cinemas reopened in the kingdom decades after they were shut. But it became clear the social change was on the prince's terms only. At the same time, dozens of women's rights activists were arrested, many who had campaigned for these very changes.
Stripped of his rock star status and viewed as impulsive, a Western boycott of this major business conference in Riyadh in October suggests the powerful prince may find it harder to court foreign investment in 2019, the crown jewel in his reform program to diversify the economy away from oil.
He'll also face growing international pressure to end the war in Yemen. And threats to his leadership within the kingdom may grow beyond the current palace whispers.
