2015 Bruneian cabinet reshuffle

[3] Most notably, the sultan appointed himself as minister of trade and foreign affairs, a role previously held by his brother, Prince Mohamed Bolkiah, since 1984.

The sultan warned that without justice, welfare and blessings would inevitably diminish, which could have influenced his decision to reorganise the cabinet and reinforce the centralisation of power.

On 21 September 2017, the PMO announced that Kamaluddin Bungsu had been appointed permanent secretary, and Jamain Julaihi was named deputy minister (energy) and industry.
