Saudi Arabia's new King Salman on Friday moved to resolve the kingdom's long term succession by appointing his nephew Mohammed bin Nayef as deputy crown prince, meaning he will be the first of that generation to rule the kingdom one day.
Prince Mohammed, who remains as Interior Minister, according to the royal decree carried on state television, is next in line to rule after Salman and Crown Prince Muqrin.
A close friend of the United States, Prince Mohammed has won plaudits from Western countries for his crushing of an al Qaeda insurgency from 2003-06 when he was head of the kingdom's security forces and his father was Interior Minister.
Born in 1959, Prince Mohammed is relatively young by the standards of senior Saudi royals, and his appointment as second in line to rule should resolve long-term questions over the succession for many years to come.
King Salman also appointed his son Mohammed bin Salman as defense minister and head of the royal court, state television said.
The king decided to keep other ministers, including in the foreign, oil and finance portfolios, in their positions, television reported citing a royal decree.
Khaled al-Tuwaijri, head of the royal court under the late King Abdullah who died earlier on Friday, was relieved of his post, state television said.
