RIYADH, (DNA) – Saudi monarch King Salman is set to step down and announce his son Crown Prince Mohammad bin Salman as his successor next week, sources said.

The 81-year-old king will continue as a ceremonial figurehead, handing over official leadership of the country to his son — often referred to as MBS.

The move is seen as the final step in the 32-year-old bin Salman’s power grab, which began earlier this month with the arrests of over 40 princes and government ministers in a corruption probe.

“Unless something dramatic happens, King Salman will announce the appointment of MBS as King of Saudi Arabia next week,” the sources said. “King Salman will play the role of the queen of England. He will only keep the title ‘Custodian of the Holy Shrines’.”
