Can Prince Saud Abdulaziz bin Ner al Saud return to Saudi Arabia or will he likely be executed if he does?

He was found guilty of murdering his servant and will be serving at least 20 years in a British prison from what i understand. They mention that the abuse had a "ual element". as of today, ity is punishable by death in Saudi Arabia. Do you think Saudi Arabian law would exercise some sort of leniency on him since hes the grandson of King Fahd, given the law doesn't change by then, or would he be treated like any other person? not really sure if the royal family gets special treatment under their government there.
