The Wall Street Journal (WSJ) had been told to submit the evidence on 1MDB to Public Accounts Committee (PAC) so it could follow up with the relevant parties at the hearing of the state-owned strategic fund.

PAC deputy chairman Dr Tan Seng Giaw made the call when he was asked to respond on the latest report by the US financial daily.

"We cannot ask questions based on allegations. We can only follow up with questions based on facts," he told Malaysiakini .
