A senior Saudi royal prince has launched an unprecedented call for change in the country’s leadership, as it faces its biggest challenge in years in the form of war, plummeting oil prices and criticism of its management of Mecca, scene of last week’s hajj tragedy.

The prince, one of the grandsons of the state’s founder, Abdulaziz Ibn Saud, has told the Guardian that there is disquiet among the royal family – and among the wider public – at the leadership of King Salman, who acceded the throne in January.

The prince, who is not named for security reasons, wrote two letters earlier this month calling for the king to be removed.

“The king is not in a stable condition and in reality the son of the king [Mohammed bin Salman] is ruling the kingdom,” the prince said. “So four or possibly five of my uncles will meet soon to discuss the letters. They are making a plan with a lot of nephews and that will open the door. A lot of the second generation is very anxious.”

“The public are also pushing this very hard, all kinds of people, tribal leaders,” the prince added. “They say you have to do this or the country will go to disaster.”
