Umno Youth wants the government to set up a royal commission of inquiry (RCI) to probe Bank Negara's losses in the foreign exchange market in 1991, when Dr Mahathir Mohamad was still the prime minister.

Umno Youth vice-chief Khairul Azwan Harun claimed that the central bank had lost US$180 billion from forex trading exposures and forex trading losses, and had gone bankrupt.
