The heir to the Saudi throne has not attended a series of high-profile ministerial and diplomatic meetings in Saudi Arabia over the last fortnight and is alleged to have been stripped of some of his financial and economic authority, the Guardian has been told.

The move to restrict, if only temporarily, the responsibilities of Crown Prince Mohammed bin Salman is understood to have been revealed to a group of senior ministers earlier last week by his father, King Salman…

The Guardian has been told Prince Mohammed did not attend two of the most recent weekly meetings of cabinet ministers, which are headed by the king.

The crown prince has also not attended other high-profile talks with visiting dignitaries, including one last week with the Russian foreign minister, Sergey Lavrov.
