Yang Dipertuan Besar Negeri Sembilan, Tuanku Jaafar Tuanku Abdul Rahman telah diisytiharkan mangkat di Hospital Tuanku Jaafar pagi ini pada pukul 11.45am. Baginda telah dilaporkan mengalami sakit dada sebelum ini. Baginda telah meninggal dunia pada umur 86 tahun

Here’s a little something that I got from the wikipedia.
The second son of Tuanku Abdul Rahman ibni Almarhum Tuanku Muhammad, Malaysia’s first Agong, he was the first of four children by his Eurasian wife Dulcie Campbell or better known as Che’ Engku Maimunah binti Abdullah. Having studied at the Malay College Kuala Kangsar, he graduated from the University of Nottingham before attending Balliol College, Oxford and the LSE. During his reign as the ruler of Negeri Sembilan, Tuanku Ja’afar focused his attention on the problems of the people and the administration of the state. In handling the socio-economic affairs of the state, Tuanku Ja’afar directed his attention to the industry and public housing sectors so as to improve the living standard of the people. As a result, several new housing areas were developed among which is Taman Tuanku Ja’afar which includes an industrial area and a golf course of international standard, Taman Tuanku Ampuan Najihah in Sungai Gadut and the Mambau housing project.

Al-Fatihah.
