Reuters on Monday reported that some members of Saudi Arabia's ruling family are agitating to prevent bin Salman from becoming king, presstv.ir reported.
Asked by CNBC about the report, Jubeir said on Wednesday, “These are outrageous comments that are being made and are totally unacceptable.”
“The Kingdom of Saudi Arabia is unified on this issue, the kingdom of Saudi Arabia is committed to its leadership, the kingdom of Saudi Arabia is committed to the vision that our leaders have put forth for us in terms of Vision 2030 and in terms of moving along the path of reform,” Jubeir said.
Reuters had quoted three sources close to the royal court as saying that 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 is still alive.
The sources said the princes recognize that the king is unlikely to turn against his favorite son. 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.
The alleged plot to overthrow bin Salman came against the backdrop of reports that the young crown prince had ordered the killing of Saudi dissident journalist Jamal Khashoggi, who was assassinated in the Saudi consulate in Istanbul on October 2.
Earlier on Monday, King Salman had also thrown his weight behind his son in his first public remarks since the killing of Khashoggi.
The king also praised bin Salman's ambitious economic reform program, whose fate is not clear anymore amid allegations of the crown prince’s direct role in the assassination.
