In this episode, we look back at a night that will have deep implications for the future of Saudi Arabia. The foreign press dubbed Saudi Crown <a href="https://www.thenational.ae/world/gcc/saudi-arabia-arrests-princes-ministers-and-business-figures-in-anti-corruption-crackdown-1.673073">Prince Mohammed bin Salman's anti-corruption drive</a> as "The night of the long knives" but many Saudis may look at his manoeuvring as a long awaited move to root out corruption. This will not only come to define the news of this week, but the news of the young Prince’s reign as he looks to push the Kingdom towards his vision. Jane Kinninmont, the senior fellow at the Middle East and North Africa programme at Chatham House, tells us how the round-up indicates a very different tone from what has transpired in Saudi Arabia in the past. Moving on to the event that kicked this week off, Dana Moukhallati, an editor on the National's foreign desk, explains how <a href="https://www.thenational.ae/world/mena/us-says-relationship-with-lebanon-will-not-change-after-hariri-resignation-1.673910">the resignation of Lebanon's prime minister, Saad Hariri</a>, might signal the end of tolerance for foreign Iranian intervention in Arab affairs. Finally, we have analysis on <a href="https://www.thenational.ae/world/mena/saudi-crown-prince-says-iran-support-to-houthis-could-be-act-of-war-1.673794">what might be a ramping up on the devastating war</a> in Yemen and how military escalation could lead to a more direct clash between Saudi Arabia and Iran.
