MCA deputy president Wee Ka Siong wants the government to set up a Royal Commission of Inquiry (RCI) for the 1MDB scandal.
Wee said this was in light of the Singapore government's decision to return RM46 million to Malaysia which was allegedly laundered from 1MDB, as well as Najib claiming that he had letters proving that the multi-billion ringgit in his bank accounts was a donation from the Saudi Arabia royal family.
"Rather than speculations on top of speculations, it is high time and only fair for the rakyat that there is an open, transparent and politically-neutral platform to learn the truth about 1MDB once and for all," he said.
Najib's account transactions are consistent with the US Department of Justice's (DOJ) claims that the former premier did receive money from "Saudi Associates 1 & 2".
However, according to the DOJ, that money originated from 1MDB and had been misappropriated.
Wee noted that the DOJ and reports by the Wall Street Journal had implicated several personalities apart from businessperson Low Taek Jho, such as officials of PetroSaudi International, International Petroleum Investment Company and Aabar Investments PJS.
"Has the government called on these foreign personalities for questioning or have they requested extradition for them to be charged here too? Are there such plans to do so?
"What is the status and progress of the April 2017 settlement agreement signed between Malaysia and the Abu Dhabi government whose resolution would mean that every single sen of missing money would be returned to 1MDB?" he said.
Wee reminded the government that setting up a royal commission of inquiry on 1MDB had been one of Pakatan Harapan's 100-day promise.
The 1MDB scandal, at present, is a subject of an investigation by multiple agencies including the MACC and police.
