Egypt's journalist and columnist Abdel Rahim Ali filed a lawsuit against entrepreneur Naguib Sawirs over insulting and defaming him in mass media, Al Bawaba News reported on Sunday. Sawirs alleged on the Youm 7 newspaper that Mr. Ali was attempting to embezzle him for financial purposes. The business tycoon also attacked the luminous writer's new programme on Al Assema TV channel as a big failure. Ali, the editor-in-chief of Al Bawaba News, resumed in May hosting his famous TV show "The Black Box" (or Flight Recorder) on Al Assema, as he continued to reveal exclusively high confidential documents regarding the banned Muslim Brotherhood group and other major public figures.
