Ahmed Qurei
Mahmoud Abbas attempted to drop him from the PA cabinet, and despite Arafat's resistance, he was replaced in April 2003. He is slated to act as Arafat's national security adviser. Al Hassan was head of Fatah's Bureau of Mobilisation and Organisation and (maktab at-ta`bia wat-tandhim) until April 2007, when he was replaced in that role by Ahmed Qurei. Al Hassan went on to become a National Security Adviser but was dropped by Mahmoud Abbas in June 2007, following his comments made on Al Jazeera.
