Amid international uproar over the killing of journalist Jamal Khashoggi, some members of Saudi Arabia’s ruling family are agitating to prevent Crown Prince Mohammed bin Salman from becoming king, Reuters reports, citing sources close to the royal court.

Dozens of princes and cousins from powerful branches of the Al Saud family want to see a change in the line of succession but would not act while King Salman - the crown prince’s 82-year-old father - is still alive, the sources said. They recognize that the king is unlikely to turn against his favorite son, known in the West as MbS.

Rather, they are discussing the possibility with other family members that after the king’s death, Prince Ahmed bin Abdulaziz, 76, a younger full brother of King Salman and uncle of the crown prince, could take the throne, according to the sources.

Prince Ahmed, King Salman’s only surviving full brother, would have the support of family members, the security apparatus and some Western powers, one of the Saudi sources said.

Prince Ahmed returned to Riyadh in October after 2-1/2 months abroad. During the trip, he appeared to criticize the Saudi leadership while responding to protesters outside a London residence chanting for the downfall of the Al Saud dynasty. He was one of only three people on the Allegiance Council, made up of the ruling family’s senior members, who opposed MbS becoming crown prince in 2017, two Saudi sources said at the time.

Neither Prince Ahmed nor his representatives could be reached for comment. Officials in Riyadh did not immediately respond to requests from Reuters for comment on succession issues.

The House of Saud is made up of hundreds of princes. Unlike typical European monarchies, there is no automatic succession from father to eldest son. Instead the kingdom’s tribal traditions dictate that the king and senior family members from each branch select the heir they consider fittest to lead.
