Saudi Arabia stands at a crucial crossroads facing unprecedented change. The Kingdom has long enjoyed seemingly inexhaustible wealth and untold power and influence. But the House of Saudi is accused of spreading extremist ideology and even supporting violent extremists. This series looks at the challenges facing the new Crown Prince, 32-year-old Mohammed bin Salman, who has pledged to transform the country.

Part 2:
This episode tells the inside story of how some of the most prominent and richest Saudi royals were caught up in the purge. The detentions opened the door on a highly secret world of kickbacks and bribes on a monumental scale, which have also embroiled many foreign governments and some of the world’s leading companies. The anti-corruption drive is led by the new crown prince, 32-year old Mohammed bin Salman, who has pledged to transform the country and to reform the country’s oil-dependent economy. But the programme hears from those who question whether the mass detentions were less about ending corruption and more about the crown prince removing any resistance to his succession to the throne.
