Crown Prince Sultan Bin Abdulaziz Al Saud of Saudi Arabia died on Saturday 22 October 2011 in New York City and was buried in the Al-Oud cemetery in Riyadh on Tuesday 25 October. 3 days later Saudi Arabia's interior minister, Prince Nayef Bin Abdulaziz Al Saud, b. 1933, was appointed as the country's new Crown Prince. He was also named prime minister, a position he will hold in addition to his post as interior minister.
In connection with the changes to the Saudi succession I have updated my website Longest reigns, which is a survey of the longest reigns among the reigning monarchs today.
The website will soon be updated once again, as Sultan Abdul Halim Mu'adzam Shah, the Sultan of Kedah, was recently elected by the Council of Rulers to be the next Yang di-Pertuan Agong (King) of Malaysia. The Sultan of Kedah will succeed as King on 13 December 2011. The Sultan of Kelantan, Sultan Muhammad V, will at the same time be installed as the next Deputy Yang di-Pertuan Agong.
