The Sultan of Johor, Ibrahim Almarhum Sultan Iskandar, was crowned yesterday at the Istana Besar in Johor Baru.
Johor is one of the Malaysian Sultanates, which still have grand coronations. The King of Malaysia, all the other Malay rulers and the Sultan of Bruni were present with their wives, most wearing official costumes and grand jewellery. The Sultan succeeded in 2010, and I am not certain why they waited until now with the ceremony.
