Saudi dissident Prince Khalid Bin Farhan Al Saud says he expects a coup to be orchestrated against King Salman and his heir, Prince Mohammed Bin Salman.

“The coming period will witness a coup against the king and the crown prince,” he said while commenting on the killing of Saudi journalist Jamal Khashoggi.

Khashoggi’s killer is known and all that is happening now are attempts to postpone a direct accusation of those who had issued the orders to have him killed, which Khalid said could be none other than Mohammed Bin Salman.

According to the prince, Khashoggi was planning to write his memoirs which could be one of the reasons that led to his murder.

Khashoggi was last seen when he entered the Saudi Consulate in Istanbul on 2 October. Turkey has said it has audio recordings which prove he was killed in the building. After first denying knowledge of Khashoggi’s whereabouts and claiming he had left the consulate 20 minutes after his arrival, Saudi authorities admitted he had been killed on site by what they described as “rogue agents”.
