Arab Digest editor William Law's guest this week is Dr Renad Mansour, senior research fellow and head of the Iraq Initiative at London's Chatham House. He has just returned from Baghdad and this wide-ranging conversation explores Iraq's political impasse and the structure that is responsible for it, the culture of violence and the enigmatic and powerful populist cleric Muqtada al-Sadr. Also on the table: Iran, Gulf neighbours, the JCPOA and climate change. Sign up NOW at ArabDigest.org for free to join the club and start receiving our daily newsletter & podcasts.
