The government yesterday launched a surprise "5-in-1" price hike programme, raising the prices of RON95 and RON97 petrol, diesel, white sugar and liquified petroleum gas (LPG), including cooking gas cyclinders, by at least 2.8 percent and as much as 15.2 percent. In fact, for white sugar, the 25 sen a kilo hike on top of the 20 sen hike in January raises its price by more than 31% this year alone.
