Political insiders in Malaysia say Prime Minister Najib Tun Razak could be facing a fresh political crisis due to the murky dealings of a sovereign fund established five years ago to drive investment in strategic domestic industries. A widening circle of critics, fed in part by exhaustive reporting on independent news sites such as Malaysiakini, say the fund may have run up as much as RM40 billion (US$12.18 billion) in debt and has few assets to show for it beyond what are described as overpriced acquisitions of independent power producers in Malaysia.
