The truth about 1MDB will not be known until a non-Umno government comes into power, according to former law minister Zaid Ibrahim.

Such a change, he said, might take years from now.

"We are a long way from reaching closure on this matter, I can assure you," he added.

Zaid was responding to the Public Accounts Committee (PAC) report on 1MDB tabled to Parliament yesterday.

As for the PAC members, the former minister praised DAP lawmaker Tony Pua for having the courage and being the exception.

"We have heard nothing from the others. They were all well selected, which is probably why they have never asked difficult questions.

"Did they ever ask Bank Negara officials to attend their hearings? No. Did they call the prime minister himself? No.

"How can anyone expect the truth to be known if the man who is the sole shareholder, sole signatory, finance minister and prime minister all at the same time doesn't say anything about what happened in 1MDB?

"These PAC members will tell you he was not called because he had no direct links to the affair, but we know how things work in this country," he added.

Zaid also noted that parliament is unable to discuss the auditor-general's report on 1MDB because it is under the Official Secrets Act.

"This, from the parliament that is supposedly being reformed. Go ahead and announce that more reforms will be implemented, as if the people believe this charade," he said.

As for 1MDB board of directors offering to resign in view of the PAC report citing poor management, Zaid believes that has been the plan from the onset.

"That means you can tell the people that all of them were responsible for the debacle and the losses, and that they must be punished.

"It's been planned to play out that way, so that blame can be placed on these directors and no one else. But it changes nothing," he added.

Prime Minister Najib Abdul Razak has repeatedly denied any wrongdoing, and blamed such allegations on those conspiring to topple him.

However, Pua, at a press conference this morning, argued that the PAC report has not cleared the prime minister, who is the chairperson of the firm's advisory board.

Meanwhile, the Institute for Democracy and Economic Affairs (Ideas) urged the authorities to probe if Najib could have exerted his influence as a "shadow director".
